Disabled Items in Vue Mention component

20 Sep 20247 minutes to read

The Mention provides options for individual items to be either in an enabled or disabled state for specific scenarios. The category of each list item can be mapped through the disabled field in the data table. Once an item is disabled, it cannot be selected as a value for the component. To configure the disabled item columns, use the fields.disabled property.

In the following sample, State are grouped according on its category using disabled field.

<template>
    <div id="app">
        <label id="comment">Comments</label>
        <div id="mentionElement" placeholder="Type @ and tag sport"></div>
        <ejs-mention id='defaultMention' :target='target' :fields='fields' :dataSource='statusData'></ejs-mention>
    </div>
</template>

<script setup>
import { MentionComponent as EjsMention } from "@syncfusion/ej2-vue-dropdowns";

const target = "#mentionElement";
const statusData = [
    { "Status": "Open", "State": false },
    { "Status": "Waiting for Customer", "State": false },
    { "Status": "On Hold", "State": true },
    { "Status": "Follow-up", "State": false },
    { "Status": "Closed", "State": true },
    { "Status": "Solved", "State": false },
    { "Status": "Feature Request", "State": false }
];
const fields = { value: 'Status', disabled: 'State' };
