21 Sep 20223 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.

import { Component, OnInit, ViewChild, ViewEncapsulation } from '@angular/core';
import { projectData } from './datasource';
import { TreeGridComponent, ColumnMenuService } from '@syncfusion/ej2-angular-treegrid';

    selector: 'app-container',
    styleUrls: ['./app/app.component.css'],
    encapsulation: ViewEncapsulation.None,
    providers: [ColumnMenuService],
    template: `<ejs-treegrid #treegrid [dataSource]='data' idMapping='TaskID' parentIdMapping='parentID' [treeColumnIndex]='1' [height]='315' showColumnMenu=true>
            <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' width='90' format="yMd" textAlign='Right' ></e-column>
            <e-column field='EndDate' headerText='End Date' width='90' format="yMd" textAlign='Right'></e-column>
            <e-column field='Duration' headerText='Duration' width='90' textAlign='Right'></e-column>
            <e-column field='Priority' headerText='Priority' width='90'></e-column>
export class AppComponent implements OnInit {

    public data: Object[] = [];

    ngOnInit(): void { = projectData;
import { NgModule,ViewChild } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { TreeGridModule } from '@syncfusion/ej2-angular-treegrid';
import { PageService, SortService, FilterService } from '@syncfusion/ej2-angular-treegrid';
import { AppComponent } from './app.component';
import {ButtonModule} from '@syncfusion/ej2-angular-buttons';

 * Module
    imports: [
    declarations: [AppComponent],

    providers: [PageService,
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
