Options

💙 You can find icons sets at Iconify

{
    // Change icon picker's theme
    theme: 'default' | 'bootstrap-5',

    // Set icon(s) library(ies)
    // iconSource: [
    //     'FontAwesome Brands 6', 
    //     'FontAwesome Solid 6', 
    //     'FontAwesome Regular 6', 
    //     'Material Design Icons', 
    //     'Iconoir', 
    //     {
    //         key: 'academicons',
    //         prefix: 'ai ai-',
    //         url: 'https://raw.githubusercontent.com/iconify/icon-sets/master/json/academicons.json'
    //     }
    // ]
    iconSource: [],

    // Close icon picker modal when icon is selected
    // If is `false` save button appear
    closeOnSelect: true,
    
    // Set a default value, preselect for example
    // icon's value and icon's name work
    defaultValue: null,
        
    // Translatable text
    i18n: {
        'input:placeholder': 'Search icon…',
            
        'text:title': 'Select icon',
        'text:empty': 'No results found…',
            
        'btn:save': 'Save'
    }
}

Events

Use the on(event, callback) and off(event, callback) functions to bind / unbind eventlistener.

Event	Description	Arguments
select	Icon is selected, return icon value, name, svg and unicode if exist	Object
save	Fired when saved with button or if closeOnSelect option is true, return return icon value, name, svg and unicode if exist	Object
loaded	All icons are loaded	void
clear	clear() method is called	void
show	Modal is shown	IconPickerInstance
hide	Modal picker is hidden	IconPickerInstance

iconPicker.on('select', instance => {
    console.log('Select:', instance);
});

Methods

After we initialize IconPicker, we have access instance. Let's look list all available methods:

Method	Description
on()	Add event handler
off()	Remove event handler
open()	Open IconPicker's modal
hide()	Remove IconPicker's modal
clear()	Clear current icon
isOpen()	Check if open or not
iconsLoaded()	Check if the icons are loaded
destroy(deleteInstance)	Set it to false (by default it is true) to not to delete IconPicker instance

Icon format setting in JSON files

While this picker uses icon sets found at Iconify, it supports an extension to their format to allow improved performance with large icon sets.

By default, those icon sets include the actual SVG directly, and the picker includes the SVG markup inline. In cases where the actual SVGs are not needed (e.g. if you're using Font Awesome and the required CSS / JavaScript is included on the page), adding a new, optional iconFormat setting to the JSON file will allow you to remove the SVGs and reduce file sizes by over 90%, making the loading of the picker much faster.

iconFormat is optional and can be set to three different values:

• svg (the default) - body must include the full SVG.

• i - body is not needed at all. The picker will use markup like <i class='far fa-abacus'></i>.

Example JSON (snipped, iconFormat can be set to "i", body can be empty or missing entirely)

{
  "prefix": "far fa-",
  "iconFormat": "i",
  "info": {
    "name": "Font Awesome Regular"
  },
  "lastModified": 1689174287,
  "icons": {
    "abacus": {
      "body": "",
      "width": 576
    },
    "acorn": {
      "width": 448
    }
  }
}

• markup - The picker uses the actual markup set in the body. This allows the use of different, custom markup for icons, e.g. <span class='far fa-abacus'></span>.

Example JSON (snipped, iconFormat must be set to "markup", body must be set)

{
  "prefix": "far fa-",
  "iconFormat": "markup",
  "info": {
    "name": "Font Awesome Regular"
  },
  "lastModified": 1689174287,
  "icons": {
    "abacus": {
      "body": "<span class='far fa-abacus'></span>",
      "width": 576
    }
  }
}

To take advantage of this, you could download the JSON file and use search-and-replace to remove the body values from the file. Then, you would need to set iconSource per the Options section above to use your new JSON file.
