Provides auto-complete suggestions for @mentions in text input fields, text areas, and content editable fields. Not fully browser tested and comes without warranty!

V2 Feature:

• Added emitter (onItemSelected) to emit selected object / list item.

To install and start the demo application:

git clone https://github.com/khan019950/angular-mentions
cd angular-mentions
npm install
ng serve

Usage

Add the package as a dependency to your project using:

npm install angular-mentions-v2

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-v2';
...

@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.
• (onItemSelected)="" event emitted with selected object whenever user select item from list.

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.

(onItemSelected) Usage

component.html :

<input type="text" [mentionConfig]="{labelKey:'name'}" (searchTerm)="serchWithTerm($event)" (onItemSelected)="itemSelected($event)">

component.ts :

.
.
.
itemSelected(item){
    console.log(item);
}
.
.
.
serchWithTerm(term){
    // you can call some service to fetch users, entity, etc by keywords or term recieved from event emitter. for e.g.
    this.someAPIservice.getUsers(term).subscribe( result => {
        console.log(result);
    });
}
.
.
