Chip customization in Angular Multi select component

27 Apr 20243 minutes to read

The MultiSelect allows the user to customize the selected chip element through the tagging event. In that event, you can set the custom classes to chip element via that event argument of setClass method.

The following sample demonstrates chip-customization with the MultiSelect component.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { FormsModule } from '@angular/forms'
import { MultiSelectModule } from '@syncfusion/ej2-angular-dropdowns'




import { Component } from '@angular/core';
import { TaggingEventArgs } from '@syncfusion/ej2-angular-dropdowns';

@Component({
imports: [
        FormsModule, MultiSelectModule
    ],


standalone: true,
    selector: 'app-root',
    template: `<ejs-multiselect id='multiselectelement' [value]='colorValues' [dataSource]='colorsData' (tagging)='onTagging($event)' [mode]='box' [placeholder]='waterMark' [fields]='fields'></ejs-multiselect>`,
})
export class AppComponent {
    // define the JSON of data
    public colorsData: { [key: string]: Object }[] = [
        { Color: 'Chocolate', Code: '#75523C' },
        { Color: 'CadetBlue', Code: '#3B8289' },
        { Color: 'DarkOrange', Code: '#FF843D' },
        { Color: 'DarkRed', Code: '#CA3832' },
        { Color: 'Fuchsia', Code: '#D44FA3' },
        { Color: 'HotPink', Code: '#F23F82' },
        { Color: 'Indigo', Code: '#2F5D81' },
        { Color: 'LimeGreen', Code: '#4CD242' },
        { Color: 'OrangeRed', Code: '#FE2A00' },
        { Color: 'Tomato', Code: '#FF745C' }
    ];

    // map the appropriate columns to fields property
    public fields: { [key: string]: string } = { text: 'Color', value: 'Code' };
    // set the value to MultiSelect
    public colorValues: [number | string] | any = ['#75523C', '#4CD242', '#FF745C'];
    // set the placeholder to MultiSelect input element
    public waterMark: string = 'Favorite Colors';
    // set the type of mode for how to visualized the selected items in input element.
    public box: string = 'Box';
    // bind the tagging event
    public onTagging = (e: TaggingEventArgs) => {
        // set the current selected item text as class to chip element.
        e.setClass((e.itemData as any)[this.fields['text']].toLowerCase());
      }

}
