Usage

Add the package as a dependency to your project using:

npm install --save ngx-ui-mention

Add the CSS to your index.html:

<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">

Add the module to your app.module imports:

import { MentionModule } from 'angular-mentions/mention';
...

@NgModule({
    imports: [ MentionModule ],
    ...
})

Add the [mention] directive to your input element:

<input type="text" [mention]="items">

Where items is a string array of the items to suggest. For example:

items: string[] = ["Noah", "Liam", "Mason", "Jacob", ...

Configuration Options

The following optional configuration items can be used.

Option	Default	Description
items		An array of strings or objects to suggest.
triggerChar	@	The character that will trigger the menu behavior.
labelKey	label	The field to be used as the item label (when the items are objects).
disableSort	false	Disable sorting of suggested items.
disableSearch	false	Disable internal filtering (only useful if async search is used).
dropUp	false	Show the menu above the cursor instead of below.
maxItems	∞	Limit the number of items shown in the text. The default is no limit.
mentionSelect		An optional function to format the selected item before inserting the text.

For Example:

<input type="text" [mention]="items" [mentionConfig]="{triggerChar:'#',maxItems:10,labelKey:'name'}">

Output Events

• (searchTerm)="" event emitted whenever the search term changes. Can be used to trigger async search.

Alternative Usage

The component can also be used by only specifying the mentionConfig object:

<input type="text" [mentionConfig]="mentionConfig">

With the following structure:

let mentionConfig = {
    items: [ "Noah", "Liam", "Mason", "Jacob", ... ],
    triggerChar: "@",
    ...
}

In this way, multiple config objects can be used:

let mentionConfig = {
    mentions: [
        {
            items: [ "Noah", "Liam", "Mason", "Jacob", ... ],
            triggerChar: '@'
        },
        {
            items: [ "Red", "Yellow", "Green", ... ],
            triggerChar: '#'
        },
    }]
}

This allows different lists and trigger characters to be configured.

Note that becuase objects are mutable, changes to the items within the config will not be picked up unless a new mentionConfig object is created.
