11 Jun 20244 minutes to read

You can customize the column menu icon by overriding the default Tree Grid class .e-icons.e-columnmenu with a custom property content as mentioned below,

    .e-treegrid .e-columnheader .e-icons.e-columnmenu::before {
        content: "\e903";
    }

In the below sample, Tree Grid is rendered with a customized column menu icon.

<template>
  <div id="app">
        <ejs-treegrid :dataSource="data" :treeColumnIndex="1" height='300px' :showColumnMenu='true' childMapping="subtasks" ref="treegrid">
        <e-columns>
          <e-column field="taskID" headerText="Task ID" width="70" textAlign="Right"></e-column>
          <e-column field="taskName" headerText="Task Name" width="100" ></e-column>
          <e-column field="startDate" headerText="Start Date" format="yMd" width="90" textAlign="Right"></e-column>
          <e-column field="endDate" headerText="End Date" width="90" format="yMd" textAlign="Center"></e-column>
          <e-column field="duration" headerText="Duration" width="90" textAlign="Right"></e-column>
          <e-column field="progress" headerText="progress" width="90" textAlign="Right"></e-column>
        </e-columns>
       </ejs-treegrid>
  </div>
</template>
<script setup>
import { provide } from "vue";

import { TreeGridComponent as EjsTreegrid, ColumnMenu, ColumnDirective as EColumn, ColumnsDirective as EColumns } from "@syncfusion/ej2-vue-treegrid";
import { sampleData } from "./datasource.js";

const data = sampleData;

provide('treegrid',  [ColumnMenu ]);

</script>
<style>
   .e-treegrid .e-columnheader .e-icons.e-columnmenu::before {
        content: "\e903";
    }

          <e-column field="taskID" headerText="Task ID" width="70" textAlign="Right"></e-column>
          <e-column field="taskName" headerText="Task Name" width="100" ></e-column>
          <e-column field="startDate" headerText="Start Date" format="yMd" width="90" textAlign="Right"></e-column>

  data() {
