Simple Angular mentions inspired by Ment.io.
Provides auto-complete suggestions for @mentions in text input fields, text areas, and content editable fields.
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 | โ | 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. | |
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> |
Event that is emitted whenever the search term changes. Can be used to trigger async search. |
@Output() opened EventEmitter<void> |
Event that is emitted when the mentions panel is opened. |
@Output() closed EventEmitter<void> |
Event that is emitted when the mentions panel is closed. |
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.
