Floating of panels in EJ2 TypeScript Dashboard Layout control

23 Jan 20256 minutes to read

The floating functionality of the control allows effective use of the entire layout for panel placement. If the floating functionality is enabled, the panels within the layout float upwards automatically to occupy the empty cells available in previous rows. This functionality can be enabled or disabled using the allowFloating property of the control.

The following sample demonstrates how to enable or disable the floating of panels in the Dashboard Layout control.

import { DashboardLayout } from '@syncfusion/ej2-layouts';
import { Button } from '@syncfusion/ej2-buttons';

// initialize Dashboard Layout control
let dashboard: DashboardLayout = new DashboardLayout({
    cellSpacing: [10, 10],
    allowFloating: false,
    cellAspectRatio: 100 / 75,
    columns: 6,
    panels: [{ '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>' }]
});
// render initialized Dashboard Layout
dashboard.appendTo('#dashboard_default');

let resetPanels = dashboard.serialize();
resetPanels[0].content = '<div class="content">0</div>';
resetPanels[1].content = '<div class="content">1</div>';
resetPanels[2].content = '<div class="content">2</div>';

let toggleBtn: Button = new Button({
    cssClass: "e-flat e-primary e-outline",
    content: "Enable Floating",
    isToggle: true
});
toggleBtn.appendTo("#toggle");
let toggleElement = document.getElementById('toggle');
if (toggleElement) {
    toggleElement.addEventListener('click', () => {
        if (toggleBtn.content == "Disable Floating and Reset") {
            toggleBtn.content = 'Enable Floating';
            dashboard.allowFloating = false;
            dashboard.panels = resetPanels;
        } else {
            toggleBtn.content = 'Disable Floating and Reset';
            dashboard.allowFloating = true;
        }
    });
}
