| --- | --- | --- |
| 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. |

| allowSpace | false | Allow spaces while mentioning. |
| returnTrigger | false | Include the trigger char in the searchTerm event. |

`html`
#### Output Events
The following output events can be used.
| Output | Description |
| --- | --- |
| @Output() searchTerm EventEmitter | Emitted whenever the search term changes. Can be used to trigger async search.@Output() itemSelected EventEmitter
| | Emitted when an item is selected.@Output() opened EventEmitter
| | Emitted when the mentions panel is opened.@Output() closed EventEmitter
| | 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:
`html`
With the following structure:
`javascript`
let mentionConfig = {
items: [ "Noah", "Liam", "Mason", "Jacob", ... ],
triggerChar: "@",
...
}
In this way, multiple config objects can be used:
`javascript``
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.
