To install and start the demo application:
git clone https://github.com/dmacfarlane/angular-mentions.git
cd angular-mentions
npm install
ng serve
Add the package as a dependency to your project using:
npm install angular-mentions
Add the module to your app.module imports:
import { MentionModule } from 'angular-mentions';
...
@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", ...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 | A function to format the selected item before inserting the text. | |
| mentionFilter | A function that returns the items to display. | |
| allowSpace | false | Allow spaces while mentioning. | 
| returnTrigger | false | Include the trigger char in the searchTerm event. | 
For Example:
<input type="text" [mention]="items" [mentionConfig]="{triggerChar:'#',maxItems:10,labelKey:'name'}">The following output events can be used.
| Output | Description | 
|---|---|
@Output() searchTerm EventEmitter<string> | 
Emitted whenever the search term changes. Can be used to trigger async search. | 
@Output() itemSelected EventEmitter<any> | 
Emitted when an item is selected. | 
@Output() opened EventEmitter<void> | 
Emitted when the mentions panel is opened. | 
@Output() closed EventEmitter<void> | 
Emitted when the mentions panel is closed. | 
The appearance of the items displayed in the mention list menu can be customized using the
[mentionListTemplate] directive as shown in this example:
https://stackblitz.com/edit/angular-mentions-avatar
Instead of using the [mentions] directive, the component can also be used by only specifying
[mentionConfig], for example:
<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 because objects are mutable, changes to the items within the config will not be picked up unless a new mentionConfig object is created.
