Column menu in Angular Treegrid component

17 Nov 202216 minutes to read

The column menu has options to integrate features like sorting, filtering, and autofit. It will show a menu with the integrated feature when users click on multiple icon of the column. To enable column menu, you need to define the showColumnMenu property as true.

To use the column menu, inject the ColumnMenu module in the treegrid.

The default items are displayed in following table.

Item Description
SortAscending Sort the current column in ascending order.
SortDescending Sort the current column in descending order.
AutoFit Auto fit the current column.
AutoFitAll Auto fit all columns.
Filter Show the filter option as given in filterSettings.type

Column menu events

During the column menu open and column menu click, the tree grid component triggers the two events as follows:

  1. The columnMenuOpen event triggers before the column menu opens.
  2. The columnMenuClick event triggers when the user clicks the column menu of the tree grid.
import { Component, OnInit, ViewChild } from '@angular/core';
import { sampleData } from './datasource';
import { ColumnMenuService } from '@syncfusion/ej2-angular-treegrid';

@Component({
    selector: 'app-container',
    template: `<ejs-treegrid #treegrid height='315' [dataSource]='data' [treeColumnIndex]='1' childMapping='subtasks' showColumnMenu="true" (columnMenuOpen)="columnMenuOpen()" (columnMenuClick)="columnMenuClick()">
                    <e-columns>
                        <e-column field='taskID' headerText='Task ID' textAlign='Right' width=100></e-column>
                        <e-column field='taskName' headerText='Task Name' textAlign='Left' width=130></e-column>

    ngOnInit(): void {
        this.data = sampleData;
    }
    columnMenuOpen() {
        alert('columnMenuOpen event is Triggered');
    }
    columnMenuClick() {
        alert('columnMenuClick event is Triggered');
    }
}

Custom column menu item

The Custom column menu items can be added by defining the columnMenuItems as a collection of the columnMenuItemModel.

Actions for these customized items can be defined in the columnMenuClick event.

import { Component, OnInit, ViewChild } from '@angular/core';
import { sampleData } from './datasource';
import { ColumnMenuService, SortService, TreeGridComponent, PageService, SortSettingsModel } from '@syncfusion/ej2-angular-treegrid';
import { MenuEventArgs } from '@syncfusion/ej2-navigations';

@Component({
    selector: 'app-container',
    template: `<ejs-treegrid #treegrid height='315' allowSorting='true' allowPaging='true' [dataSource]='data' [treeColumnIndex]='1' childMapping='subtasks' [sortSettings]='sortSettings' showColumnMenu="true" [columnMenuItems]='columnMenuItems'>
                    <e-columns>
                        <e-column field='taskID' headerText='Task ID' textAlign='Right' width=140></e-column>
                        <e-column field='taskName' headerText='Task Name' textAlign='Left' width=160></e-column>
                        <e-column field='startDate' headerText='Start Date' textAlign='Right' format='yMd' width=160></e-column>
                        <e-column field='duration' headerText='Duration' textAlign='Right' width=150></e-column>
                        <e-column field='progress' headerText='Progress' textAlign='Right' width=150></e-column>
                    </e-columns>
                </ejs-treegrid>`,
    providers: [SortService, ColumnMenuService, PageService]
})
export class AppComponent implements OnInit {

    @ViewChild('treegrid')
    public treegrid: TreeGridComponent;
    public data: object[];
    public columnMenuItems: any = [{ text: 'Clear Sorting', id: 'treegridclearsorting' }];
    public sortSettings: SortSettingsModel =  {columns: [{direction: 'Descending', field: 'taskID'}]};
    public columnMenuClick(args: MenuEventArgs) {
        if (args.item.id === 'treegridclearsorting') {
            this.treegrid.clearSorting();
        }
    }
    ngOnInit(): void {
        this.data = sampleData;
    }

Customize menu items for particular columns

Sometimes, you have a scenario that hides an item from the column menu for particular columns. In that case, define the columnMenuOpenEventArgs.hide as true in the columnMenuOpen event.

In the following sample, the Filter item was hidden in the column menu when opened for the taskName column.

import { Component, OnInit, ViewChild } from '@angular/core';
import { sampleData } from './datasource';
import { TreeGridComponent, SortService, ColumnMenuService, PageService, FilterService } from '@syncfusion/ej2-angular-treegrid';
import { ColumnMenuItemModel, ColumnMenuOpenEventArgs, FilterSettingsModel } from '@syncfusion/ej2-angular-treegrid';

@Component({
    selector: 'app-container',
    template: `<ejs-treegrid #treegrid height='315' allowSorting='true' allowPaging='true' [dataSource]='data' [treeColumnIndex]='1' childMapping='subtasks' [filterSettings]='filterSettings' (columnMenuOpen)='columnMenuOpen($event)' [allowFiltering]='true' showColumnMenu="true">
        <e-columns>
            <e-column field='taskID' headerText='Task ID' textAlign='Right' width=140></e-column>
            <e-column field='taskName' headerText='Task Name' textAlign='Left' width=160></e-column>
            <e-column field='startDate' headerText='Start Date' textAlign='Right' format='yMd' width=160></e-column>
            <e-column field='duration' headerText='Duration' textAlign='Right' width=150></e-column>
            <e-column field='progress' headerText='Progress' textAlign='Right' width=150></e-column>
        </e-columns>
    </ejs-treegrid>`,
    providers: [SortService, ColumnMenuService, PageService, ColumnMenuService, FilterService]
})
export class AppComponent implements OnInit {

    @ViewChild('treegrid')
    public treegrid: TreeGridComponent;
    public data: object[];
    public filterSettings: FilterSettingsModel = { type: 'Menu' };
    public columnMenuOpen(args: ColumnMenuOpenEventArgs) {
        for (const item of args.items) {
            if (item.text === 'Filter' && args.column.field === 'taskName') {
                (item as ColumnMenuItemModel).hide = true;
            } else {
                (item as ColumnMenuItemModel).hide = false;
            }
        }
    }

    ngOnInit(): void {
        this.data = sampleData;
