Resizing in Angular AutoComplete component

15 Dec 20245 minutes to read

You can dynamically adjust the size of the popup in the Autocomplete component by using the AllowResize property. When enabled, users can resize the popup, improving visibility and control, with the resized dimensions being retained across sessions for a consistent user experience.

The following sample illustrates the implementation of the Popup Resize feature.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { FormsModule, ReactiveFormsModule } from '@angular/forms'
import { AutoCompleteModule } from '@syncfusion/ej2-angular-dropdowns'
import { ButtonModule } from '@syncfusion/ej2-angular-buttons'




import { Component, HostListener, ViewChild } from '@angular/core';
import { AutoCompleteComponent } from '@syncfusion/ej2-angular-dropdowns';
@Component({
    imports: [
        FormsModule, ReactiveFormsModule, AutoCompleteModule, ButtonModule
    ],


    standalone: true,
    selector: 'app-root',
    // specifies the template string for the AutoComplete component
    template: `<ejs-autocomplete id='atcelement' [allowResize]='allowResize' #samples [dataSource]='statusData' [fields]='fields' [placeholder]='text'></ejs-autocomplete>`
})
export class AppComponent {
    @ViewChild('samples')
    public status?: AutoCompleteComponent;
    constructor() {
    }
    public statusData: { [key: string]: Object }[] = [
        { "Status": "Open", "State": false },
        { "Status": "Waiting for Customer", "State": false },
        { "Status": "On Hold", "State": true },
        { "Status": "Follow-up", "State": false },
        { "Status": "Closed", "State": true },
        { "Status": "Solved", "State": false },
        { "Status": "Feature Request", "State": false },
        { "Status": "In Progress", "State": false },
        { "Status": "Pending", "State": true },
        { "Status": "Escalated", "State": true },
        { "Status": "New", "State": false },
        { "Status": "Under Review", "State": true },
        { "Status": "Reopened", "State": false },
        { "Status": "Approved", "State": true },
        { "Status": "Awaiting Approval", "State": false },
        { "Status": "Scheduled", "State": false },
        { "Status": "Canceled", "State": true },
        { "Status": "Completed", "State": true },
        { "Status": "Acknowledged", "State": false },
        { "Status": "In Development", "State": false }
    ];
    // maps the appropriate column to fields property
    public fields: Object = { value: 'Status' };
    // set true for enable the resize property to AutoComplete
    public allowResize: boolean = true;
    //set the placeholder to AutoComplete input
    public text: string = "Select Status";
    @HostListener('document:keyup', ['$event'])
    handleKeyboardEvent(event: KeyboardEvent) {
        if (event.altKey && event.keyCode === 84 /* t */) {
            // press alt+t to focus the control.
            this.status!.focusIn();
        }
    }
}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));
