lightweight, efficient Tags input component in Vanilla JS / React / Angular [super customizable, tiny size & top performance]
Transforms an input field or a textarea into a Tags component, in an easy, customizable way,
with great performance and small code footprint, exploded with features.
Vanilla ⚡ React ⚡ Vue ⚡ Angular
Place these lines before any other code which is (or will be) using Tagify (Example here)
<script src="https://cdn.jsdelivr.net/npm/@yaireo/tagify"></script>
<script src="https://cdn.jsdelivr.net/npm/@yaireo/tagify/dist/tagify.polyfills.min.js"></script>
<link href="https://cdn.jsdelivr.net/npm/@yaireo/tagify/dist/tagify.css" rel="stylesheet" type="text/css" />
Tagify will then be available globally.
To load specific version use @ - for example: unpkg.com/@yaireo/tagify@3.1.0
npm i @yaireo/tagify --save
import Tagify from '@yaireo/tagify'
var inputElem = document.querySelector('input') // the 'input' element which will be transformed into a Tagify component
var tagify = new Tagify(inputElem, {
// A list of possible tags. This setting is optional if you want to allow
// any possible tag to be added without suggesting any to the user.
whitelist: ['foo', 'bar', 'and baz', 0, 1, 2]
})
The above example shows the most basic whitelist array setting possible, with a mix
of Strings and Numbers but the array also support Objects whic a must-have property of value:
whitelist: [{value: 'foo', id: '123', email: 'foo@whatever.com'}, ...]
The value property is what will be used when actually defining the value property of the original input element (inputElem in the example above) which was transformed
into a Tagify component, and so when the form data is sent to the server, it will contain all the values (which are the selected tags in the component).
For selected tags to show a different text than what is defined in value for a whitelist item, see the tagTextProp setting
⚠️ Important:
Don't forget to include tagify.css file in your project.
CSS location: @yaireo/tagify/dist/tagify.css
SCSS location: @yaireo/tagify/src/tagify.scss
See SCSS usecase & example
There are several places in the source code which emits console.warn logs to help identify issues.
Those will only work if .
To disable the default logging, set the following global variable:Tagify.logger.enabled flag is set to true
window.TAGIFY_DEBUG = false
var tagify = new Tagify(...)

var tagify = new Tagify(...);
tagify.addTags(["banana", "orange", "apple"])
// or add tags with pre-defined properties
tagify.addTags([{value:"banana", color:"yellow"}, {value:"apple", color:"red"}, {value:"watermelon", color:"green"}])
There are two possible ways to get the value of the tags:
value prop: tagify.value (Array of tags)inputElm.value (Stringified Array of tags)The most common way is to simply listen to the change event on the original input
var inputElm = document.querySelector,
tagify = new Tagify (inputElm);
inputElm.addEventListener('change', onChange)
function onChange(e){
// outputs a String
console.log(e.target.value)
}
Default format is a JSON string:
'[{"value":"cat"}, {"value":"dog"}]'
I recommend keeping this because some situations might have values such as addresses (tags contain commas):
'[{"value":"Apt. 2A, Jacksonville, FL 39404"}, {"value":"Forrest Ray, 191-103 Integer Rd., Corona New Mexico"}]'
Another example for complex tags state might be disabled tags, or ones with custom identifier class:
(tags can be clicked, so delevopers can choose to use this to disable/enable tags)
'[{"value":"cat", "disabled":true}, {"value":"dog"}, {"value":"bird", "class":"color-green"}]'
To change the format, assuming your tags have no commas and are fairly simple:
var tagify = new Tagify(inputElm, {
originalInputValueFormat: valuesArr => valuesArr.map(item => item.value).join(',')
})
Output:
"cat,dog"
Dynamically-loaded suggestions list (whitelist) from the server (as the user types) is a frequent need to many.
Tagify comes with its own loading animation, which is a very lightweight CSS-only code, and the loading
state is controlled by the method tagify.loading which accepts true or false as arguments.
Below is a basic example using the fetch API. I advise aborting the last request on any input before starting a new request.
var input = document.querySelector('input'),
tagify = new Tagify(input, {whitelist:[]}),
controller; // for aborting the call
// listen to any keystrokes which modify tagify's input
tagify.on('input', onInput)
function onInput( e ){
var value = e.detail.value
tagify.whitelist = null // reset the whitelist
// https://developer.mozilla.org/en-US/docs/Web/API/AbortController/abort
controller && controller.abort()
controller = new AbortController()
// show loading animation.
tagify.loading(true)
fetch('http://get_suggestions.com?value=' + value, {signal:controller.signal})
.then(RES => RES.json())
.then(function(newWhitelist){
tagify.whitelist = newWhitelist // update whitelist Array in-place
tagify.loading(false).dropdown.show(value) // render the suggestions dropdown
})
}
Sometimes the whitelist might be loaded asynchronously, and so any pre-filled value in the original input field
will be removed if the enforceWhitelist is set to true.
Tagify can automatically restore the last used whitelist by setting a unique id to the Tagify instance,
by using the localstorage to persist the whitelist & value data:
var input = document.querySelector('input'),
tagify = new Tagify(input, {
id: 'test1', // must be unique (per-tagify instance)
enforceWhitelist: true,
}),
Tags that aren't read-only can be edited by double-clicking them (by default)
or by changing the editTags setting to 1, making tags editable by single-clicking them.
The value is saved on blur or by pressing enter key. Pressing Escape will revert the change trigger blur.
ctrlz will revert the change if an edited tag was marked as not valid (perhaps duplicate or blacklisted)
To prevent all tags from being allowed to be editable, set the editTags setting to false (or null).
To do the same but for specific tag(s), set those tags' data with editable property set to false:
<input value='[{"value":"foo", "editable":false}, {"value":"bar"}]'>
For "regular" tags (not mix-mode or select-mode) the easiest way is to use the pattern setting and use a Regex, or
apply the pattern attribute directly on the input which will be "transformed" into a Tagify component (for vanilla code where the input tag is fully accessible to developers).
If the pattern setting does not meet your needs, use the validate setting, which recieves a tag data object as an argument and should return true if validaiton is passing, or false/string of not.
A string may be returned as the reason of the validation failure so it would be printed as the title attribute of the invalid tag.
Here's an example for async validation for an added tag. The idea is to listen to "add" event,
and when it fires, first set the tag to "loading" state, run an async call, and then set the loading state (of the tag) back to false.
If the custom async validation failed, call the replaceTag Tagify method and set the __isValid tag data property to the error string which will
be shown when hovering the tag.
Note - there is a setting to keep invalid tags (keepInvalidTags) and if it's set to true, the user can see the reason for the invalidation by
hovering the tag and see the browser's native tooltip via the title attribute:
{
empty : "empty",
exceed : "number of tags exceeded",
pattern : "pattern mismatch",
duplicate : "already exists",
notAllowed : "not allowed"
}
The texts for those (invalid tags) titles can be customized from the settings:
new Tagify(inputElement, {
texts: {
duplicate: "Duplicates are not allowed"
}
})
Or by directly manipulating the Tagify function prototype:
Tagify.prototype.TEXTS = {...Tagify.prototype.TEXTS, {duplicate: "Duplicates are not allowed"}}
To be able to sort tags by dragging, a 3rd-party script is needed.
I have made a very simple drag & drop (~11kb unminified) script which uses HTML5 native API and
it is available to download via NPM or Github
but any other drag & drop script may work. I could not find on the whole internet a decent lightweight script.
var tagify = new Tagify(inputElement)
// bind "DragSort" to Tagify's main element and tell
// it that all the items with the below "selector" are "draggable"
var dragsort = new DragSort(tagify.DOM.scope, {
selector: '.'+tagify.settings.classNames.tag,
callbacks: {
dragEnd: onDragEnd
}
})
// must update Tagify's value according to the re-ordered nodes in the DOM
function onDragEnd(elm){
tagify.updateValueByDOMTags()
}
It's possible to control the templates for some of the HTML elements Tagify is using by
modifying the settings.templates Object with your own custom functions which must return an HTML string.
Available templates are: wrapper, input, tag, dropdown, dropdownItem, dropdownContent, dropdownHeader, dropdownFooter and the optional dropdownItemNoMatch
which is a special template for rendering a suggestion item (in the dropdown list) only if there were no matches found for the typed input, for example:
// ...more tagify settings...
templates: {
dropdownItemNoMatch: data =>
`<div class='${tagify.settings.classNames.dropdownItem}' value="noMatch" tabindex="0" role="option">
No suggestion found for: <strong>${data.value}</strong>
</div>`
}
tag template:Each template function is automatically binded with this pointing to the current Tagify instance.
It is imperative to preserve the class names and also the this.getAttributes(tagData) for proper functionality.
new Tagify(inputElem, {
templates: {
tag(tagData, tagify){
return `<tag title="${(tagData.title || tagData.value)}"
contenteditable='false'
spellcheck='false'
tabIndex="${this.settings.a11y.focusableTags ? 0 : -1}"
class="${this.settings.classNames.tag} ${tagData.class ? tagData.class : ""}"
${this.getAttributes(tagData)}>
<x title='' class="${this.settings.classNames.tagX}" role='button' aria-label='remove tag'></x>
<div>
<span class="${this.settings.classNames.tagText}">${tagData[this.settings.tagTextProp] || tagData.value}</span>
</div>
</tag>`,
dropdownFooter(suggestions){
var hasMore = suggestions.length - this.settings.dropdown.maxItems;
return hasMore > 0
? `<footer data-selector='tagify-suggestions-footer' class="${this.settings.classNames.dropdownFooter}">
${hasMore} more items. Refine your search.
</footer>`
: '';
}
}
})
The suggestions list is a whitelist Array of Strings or Objects which was set in the settings Object when the Tagify instance was created, and can be set later directly on the instance: tagifyInstance.whitelist = ["tag1", "tag2", ...].
The suggestions dropdown will be appended to the document's <body> element and will be rendered by default in a position below (bottom of) the Tagify element.
Using the keyboard arrows up/down will highlight an option from the list, and hitting the Enter key to select.
It is possible to tweak the list dropdown via 2 settings:
enabled - this is a numeral value that tells Tagify when to show the suggestions dropdown, when a minimum of N characters were typed.maxItems - Limits the number of items the suggestions list will rendervar input = document.querySelector('input'),
tagify = new Tagify(input, {
whitelist : ['aaa', 'aaab', 'aaabb', 'aaabc', 'aaabd', 'aaabe', 'aaac', 'aaacc'],
dropdown : {
classname : "color-blue",
enabled : 0, // show the dropdown immediately on focus
maxItems : 5,
position : "text", // place the dropdown near the typed text
closeOnSelect : false, // keep the dropdown open after selecting a suggestion
highlightFirst: true
}
});
Will render
<div class="tagify__dropdown tagify__dropdown--text" style="left:993.5px; top:106.375px; width:616px;">
<div class="tagify__dropdown__wrapper">
<div class="tagify__dropdown__item tagify__dropdown__item--active" value="aaab">aaab</div>
<div class="tagify__dropdown__item" value="aaabb">aaabb</div>
<div class="tagify__dropdown__item" value="aaabc">aaabc</div>
<div class="tagify__dropdown__item" value="aaabd">aaabd</div>
<div class="tagify__dropdown__item" value="aaabe">aaabe</div>
</div>
</div>
By default searching the suggestions is using fuzzy-search (see settings).
If you wish to assign alias to items (in your suggestion list), add the searchBy property to whitelist items you wish
to have an alias for.
In the below example, typing a part of a string which is included in the searchBy property, for example land midd" -
the suggested item which matches the value "Israel" will be rendered in the suggestions (dropdown) list.
whitelist = [
...
{ value:'Israel', code:'IL', searchBy:'holy land, desert, middle east' },
...
]
Another handy setting is dropdown.searchKeys which, like the above dropdown.searchBy setting, allows
expanding the search of any typed terms to more than the value property of the whitelist items (if items are a Collection).
[
{
value : 123456,
nickname : "foo",
email : "foo@mail.com"
},
{
value : 987654,
nickname : "bar",
email : "bar@mail.com"
},
...more..
]
Modified searchKeys setting to also search in other keys:
{
dropdown: {
searchKeys: ["nickname", "email"] // fuzzy-search matching for those whitelist items' properties
}
}
This feature must be toggled using these settings:
{
// mixTagsInterpolator: ["{{", "}}"], // optional: interpolation before & after string
mode: 'mix', // <-- Enable mixed-content
pattern: /@|#/ // <-- Text starting with @ or # (if single, String can be used here instead of Regex)
}
When mixing text with tags, the original textarea (or input) element will have a value as follows:
[[cartman]] and [[kyle]] do not know [[Homer simpson]]
If the initial value of the textarea or input is formatted as the above example, Tagify will try to
automatically convert everything between [[ & ]] to a tag, if tag exists in the whitelist, so make
sure when the Tagify instance is initialized, that it has tags with the correct value property that match
the same values that appear between [[ & ]].
Applying the setting dropdown.position:"text" is encouraged for mixed-content tags, because the suggestions list
weird when there is already a lot of content on multiple lines.
If a tag does not exist in the whitelist, it may be created by the user and all you should do is listen to the add event and update your local/remote state.
Similar to native <Select> element, but allows typing text as value.
See live demo for React integration examples. ⚠️ Tagify is not a controlled component.
A none-minified and raw source-code Tagify React component is exported from react.tagify.jsx and you can import it as seen in the below code example.
This React port will only work if your bundler can handle raw source-code in ES2015+ which is better for tree-shaking.
onChange prop:I have changed how the onChange works internally within the Wrapper of Tagify
so as of March 30, 2021 the e argument will include a detail parameter with the value as string.
There is no more e.target, and to access the original DOM input element, do this: e.detail.tagify.DOM.originalInput.
Note: You will need to import Tagify's CSS also, either by JavaScript or by SCSS
@import(which is preferable) Also note that you will need to use dart-sass and not node-sass in order to compile the file.
import { useCallback, useRef } from 'react'
import Tags from '@yaireo/tagify/react' // React-wrapper file
import '@yaireo/tagify/dist/tagify.css' // Tagify CSS
const App = () => {
// on tag add/edit/remove
const onChange = useCallback((e) => {
console.log("CHANGED:"
, e.detail.tagify.value // Array where each tag includes tagify's (needed) extra properties
, e.detail.tagify.getCleanValue() // Same as above, without the extra properties
, e.detail.value // a string representing the tags
)
}, [])
return (
<Tags
whitelist={['item 1', 'another item', 'item 3']}
placeholder='Add some tags'
settings={{
blacklist: ["xxx"],
maxTags: 4,
dropdown: {
enabled: 0 // always show suggestions dropdown
}
}}
defaultValue="a,b,c" // initial value
onChange={onChange}
/>
)
}
To gain full access to Tagify's (instance) inner methods, A custom ref can be used:
import Tags, {MixedTags} from "@yaireo/tagify/react";
...
const tagifyRef = useRef()
...
<Tags tagifyRef={tagifyRef} ... />
// or mix-mode
<MixedTags
settings={...}
onChange={...}
defaultValue={`This is a textarea which mixes text with [[{"value":"tags"}]].`}
/>
<MixedTags> component is a shorthand for <Tags InputMode="textarea">
The settings prop is only used once in the initialization process, please do not update it afterwards.

I don't know Vue at all and this thin wrapper was built by a friend who knows.
To import the wrapper file, use the import path @yaireo/tagify/vue
This variant of Tagify code has been deprecated because it doesn't really add much in terms of ease-of-use. I only made it so it would be possible to use jQuery selectors & chaining but the (jQuery) port really isn't needed when implementing Tagify within a jQuery code.
Below is the documentation for previous Tagify packages versions which included support:
jQuery.tagify.jsA jQuery wrapper version is also available, but I advise not using it because it's basically the exact same as the "normal" script (non-jqueryfied) and all the jQuery's wrapper does is allowing to chain the event listeners for ('add', 'remove', 'invalid')
$('[name=tags]')
.tagify()
.on('add', function(e, tagData){
console.log('added', ...tagData) // data, index, and DOM node
});
Accessing methods can be done via the .data('tagify'):
$('[name=tags]').tagify();
// get tags from the server (ajax) and add them:
$('[name=tags]').data('tagify').addTags('aaa, bbb, ccc')
The below list of attributes affect Tagify.
These can also be set by Tagify settings Object manually, and not declerativly (via attributes).
| Attribute | Example | Info |
|---|---|---|
| pattern | | Tag Regex pattern which tag input is validated by. |
| placeholder | | This attribute's value will be used as a constant placeholder, which is visible unless something is being typed. |
| readOnly | | No user-interaction (add/remove/edit) allowed. |
| autofocus | | Automatically focus the the Tagify component when the component is loaded |
| required | | Adds a required attribute to the Tagify wrapper element. Does nothing more. |
<input> wrapped in a <label> doesn't work - #1219 and so Tagify internally sets the label's for attribute to an empty string, so clicking the Tagify component will not blur it and re-focus on the hidden input/textarea element Tagify is "connected" toList of questions & scenarios which might come up during development with Tagify:
const tagify = new Tagify(tagNode, {
whitelist: ["a", "b", "c"]
})
If changes to the whitelist are needed, they should be done like so:
Incorrect:
tagify.settings.whitelist = ["foo", "bar"]
Correct:
// set the whitelist directly on the instance and not on the "settings" property
tagify.whitelist = ["foo", "bar"]
Tagify does not accept just any kind of data structure.
If a tag data is represented as an Object, it must contain a unique property value
which Tagify uses to check if a tag already exists, among other things, so make sure it is present.
Incorrect:
[{ "id":1, "name":"foo bar" }]
Correct:
[{ "id":1, "value": 1, "name":"foo bar" }]
[{ "value":1, "name":"foo bar" }]
[{ "value":"foo bar" }]
// ad a simple array of Strings
["foo bar"]
In framework-less projects, the developer should save the state of the Tagify component (somewhere), and
the question is:
when should the state be saved?
On every change made to Tagify's internal state (tagify.value via the update() method).
var tagify = new Tagify(...)
// listen to "change" events on the "original" input/textarea element
tagify.DOM.originalInput.addEventListener('change', onTagsChange)
// This example uses async/await but you can use Promises, of course, if you prefer.
async function onTagsChange(e){
const {name, value} = e.target
// "imaginary" async function "saveToServer" should get the field's name & value
await saveToServer(name, value)
}
If you are using React/Vue/Angular or any "modern" framework, then you already know how to
attach "onChange" event listeners to your <input>/<textarea> elements, so the above is irrelevant.
Stopping tags from wrapping to new lines, add this to your .tagify selector CSS Rule:
flex-wrap: nowrap;
Tagify internally has state property, per Tagify instance
and this may be useful for a variety of things when implementing a specific scenario.
var tagify = new Tagify(...)
var formElm = document.forms[0]; // just an example
tagify.on('keydown', onTagifyKeyDown)
function onTagifyKeyDown(e){
if( e.key == 'Enter' && // "enter" key pressed
!tagify.state.inputText && // assuming user is not in the middle or adding a tag
!tagify.state.editing // user not editing a tag
){
setTimeout(() => formElm.submit()) // put some buffer to make sure tagify has done with whatever, to be on the safe-side
}
}

Tagify's utilizes CSS variables which allow easy customization without the need to manually write CSS. If you do wish to heavily style your Tagify components, then you can (and should) use the below variables within your modified styles as much as you can.
For a live example, see the demos page.

Tagify is prototype based and There are many methods, but I've chosen to list the most relevant ones:
| Name | Parameters | Info |
|---|---|---|
destroy | Reverts the input element back as it was before Tagify was applied | |
removeAllTags | Removes all tags and resets the original input tag's value property | |
addTags |
| Accepts a String (word, single or multiple with a delimiter), an Array of Objects (see above) or Strings. |
addMixTags | Array/String | Bypasses the normalization process in addTags, forcefully adding tags at the last caret location or at the end, if there's no last caret location saved (at tagify.state.selection) |
removeTags |
| (#502) Remove single/multiple Tags. When nothing passed, removes last tag.
|
addEmptyTag | Object (tagData) | Create an empty tag (optionally with pre-defined data) and enters "edit" mode directly. See demo |
loadOriginalValues | String/Array | Converts the input's value into tags. This method gets called automatically when instansiating Tagify. Also works for mixed-tags |
getWhitelistItemsByValue | Object | {value} - return an Array of found matching items (case-insensitive) |
getTagIndexByValue | String | Returns the index of a specific tag, by value |
getTagElmByValue | String | Returns the first matched tag node, if found |

loading | Boolean | toggle loading state on/off (Ex. AJAX whitelist pulling) |
tagLoading | HTMLElement, Boolean | same as above but for a specific tag element |
createTagElem | Object (tagData) | Returns a tag element from the supplied tag data |

To listen to tagify events use the .on(EVENT_NAME, EVENT_CALLBACK_REFERENCE) method and stop listening use the .off(EVENT_NAME, EVENT_CALLBACK_REFERENCE)
All triggered events return the instance's scope (tagify).
See e.detail for custom-event additional data.
var tagify = new Tagify(...)
// events can be chainable, and multiple events may be binded for the same callback
tagify
.on('input', onInput)
.on('edit:input edit:updated edit:start edit:keydown', e => console.log(e.type, e.detail))
function onInput(e) {
console.log(e.detail)
}
// later in the code you might do to unsubscribe the event listener with a specific callback
tagify.off('input', onInput)
var tagify = new Tagify(inputNode, {
callbacks: {
"change": (e) => console.log(e.detail),
"dropdown:show": (e) => console.log(e.detail)
}

Promise-based hooks for async program flow scenarios.
Allows to "hook" (intervene) at certain points of the program, which were selected as a suitable place to pause the program flow and wait for further instructions on how/if to proceed.
var input = document.querySelector('input')
var tagify = new Tagify(input,{
hooks: {
/**
* Removes a tag
* @param {Array} tags [Array of Objects [{node:..., data:...}, {...}, ...]]
*/
beforeRemoveTag : function( tags ){
return new Promise((resolve, reject) => {
confirm("Remove " + tags[0].data.value + "?")
? resolve()
: reject()
})
}
}
})
| Name | Parameters | Info |
|---|---|---|
| beforeRemoveTag | Array (of Objects) | Example |
| suggestionClick | Object (click event data) | Example |
| beforePaste | tagify, pastedText, clipboardData | Before pasted text was added to Tagify. Resolve with new paste value if needed |
| beforeKeyDown | On any browser keydown event, but called after keydown Tagify event |
| Name | Type | Default | Info |
|---|---|---|---|
| id | String | See Persisted data | |
| tagTextProp | String | "value" | Tag data Object property which will be displayed as the tag's text. Remember to keep "value" property unique. See Also: dropdown.mapValueTo, dropdown.searchKeys |
| placeholder | String | Placeholder text. If this attribute is set on an input/textarea element it will override this setting | |
| delimiters | String | "," | [RegEx string] split tags by any of these delimiters. Example delimeters: ",|.| " (comma, dot or whitespace) |
| pattern | String/RegEx | null | Validate input by RegEx pattern (can also be applied on the input itself as an attribute) Ex: /[1-9]/ |
| mode | String | null | Use select for single-value dropdown-like select box. See mix as value to allow mixed-content. The 'pattern' setting must be set to some character. |
| mixTagsInterpolator | Array | ['[[', ']]'] | Interpolation for mix mode. Everything between these will become a tag |
| mixTagsAllowedAfter | RegEx | /,|\.|\:|\s/ | Define conditions in which typed mix-tags content is allowing a tag to be created after. |
| duplicates | Boolean | false | Should duplicate tags be allowed or not |
| trim | Boolean | true | If true trim the tag's value (remove before/after whitespaces) |
| enforceWhitelist | Boolean | false | Should ONLY use tags allowed in whitelist. In mix-mode, setting it to false will not allow creating new tags. |

| addTagOnBlur | Boolean | true | Automatically adds the text which was inputed as a tag when blur event happens |
| addTagOn | Array | ['blur', 'tab', 'enter'] | If the tagify field (in a normal mode) has any non-tag input in it, convert it to a tag on any of these "events": blur away from the field, click "tab"/"enter" key |
