How to change the color of a selected item in JavaScript Menu?
This knowledge base explains how to highlight the selected item in JavaScript Menu. It can be achieved by adding the ‘e-select’ class to the selected menu item using the select event in menu. Whenever the required item is selected in the menu, it will be highlighted by the specified color. In the following code example, we have provided the color to be added in the select event if the item is selected.
[App.component.ts]
import { Component } from '@angular/core';
import { MenuItemModel, MenuEventArgs } from '@syncfusion/ej2-angular-navigations';
@Component({
selector: 'my-app',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
public menuItems: MenuItemModel[] = [
{
text: 'File',
iconCss: 'em-icons e-file'
},
{
text: 'Edit',
iconCss: 'em-icons e-edit'
},
{
text: 'View'
},
{
text: 'Tools'
},
{
text: 'Help'
}
];
// Triggers when the menu item is selected
private select(args: MenuEventArgs): void {
// ‘e- selected’ class was added to the selected menu item if (!args.element.parentElement.querySelector(‘.e-select’))
args.element.classList.add('e-select');
} else{
args.element.parentElement.querySelector(‘.e-select’).classList.remove(‘e-select’);
args.element.classList.add('e-select');
}
}
}
[App.component.html]
<div class="menu-control"> <ejs-menu [items]="menuItems" (select)="select($event)" ></ejs-menu> </div>
[App.component.css]
.e-color{
background-color: goldenrod;
}
.menu-control{
margin-top: 45px;
text-align: centre;
}
