Floating Panels in JavaScript (ES5) Dashboard Layout control

The floating functionality of the component allows 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.

var dashboard  = new ej.layouts.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>'}]
    });

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

resetPanels[2].content = '<div class="content">2</div>';

var toggleBtn = new ej.buttons.Button({

    } else {
        toggleBtn.content = 'Disable Floating and Reset';
        dashboard.allowFloating = true;
