Floating of panels in Angular Dashboard layout component

27 Apr 20244 minutes to read

The floating functionality of the component allows you to effectively use the entire layout for the panel’s placement. If the floating functionality is enabled, the panels within the layout get floated upwards automatically to occupy the empty cells available in previous rows. This functionality can be enabled or disabled using the allowFloating property of the component.

The following sample demonstrates how to enable or disable the floating of panels in the DashboardLayout component.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { DashboardLayoutModule } from '@syncfusion/ej2-angular-layouts'
import { ButtonModule } from '@syncfusion/ej2-angular-buttons'



import { Component, ViewChild, ViewEncapsulation } from '@angular/core';
import { DashboardLayoutComponent } from '@syncfusion/ej2-angular-layouts';
import { ButtonComponent } from '@syncfusion/ej2-angular-buttons';

@Component({
imports: [ DashboardLayoutModule, ButtonModule],


standalone: true,
    selector: 'app-root',
    styleUrls: ['./default-style.css'],
    template: `
    <div class="control-section">
        <div class="inline" id="control">
            <ejs-dashboardlayout id='dashboard_default' #defaultLayout [columns]='6' [cellSpacing]='cellSpacing'
                [panels]='panels' [allowFloating]='allowFloating' [cellAspectRatio]='cellAspectRatio'>
            </ejs-dashboardlayout>
        </div>
        <div class="inline" id="properties">
            <button ejs-button id='toggle' #toggleBtn cssClass="e-flat e-primary e-outline" [isToggle]="true" (click)='btnClick($event)' content="Enable Floating"></button>
        </div>
    </div>`,
    encapsulation: ViewEncapsulation.None
})
export class AppComponent {
    @ViewChild('defaultLayout') dashboard?: DashboardLayoutComponent;
    @ViewChild('toggleBtn') toggleBtn?: ButtonComponent;
    public cellSpacing: any = [10, 10];
    public allowFloating: boolean = false;
    public cellAspectRatio: number = 100/75;
    public panels: any = [
    {'sizeX': 2, 'sizeY': 2, 'row': 1, 'col': 0, content:'<div class="content">0</div>'},
    {'sizeX': 2, 'sizeY': 2, 'row': 2, 'col': 2, content:'<div class="content">1</div>'},
    {'sizeX': 2, 'sizeY': 2, 'row': 3, 'col': 4, content:'<div class="content">2</div>'}
    ];

    btnClick(args: any) {
        if (this.toggleBtn?.content == "Disable Floating and Reset") {
            this.toggleBtn!.content = 'Enable Floating';
            this.dashboard!.allowFloating = false;
            this.dashboard!.panels = this.panels;
        } else {
            this.toggleBtn!.content = 'Disable Floating and Reset';
            this.dashboard!.allowFloating = true;
        }
    }
}

main.ts

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