Floating of panels in EJ2 JavaScript Dashboard layout control

8 May 20234 minutes to read

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.

index.js
index.html
// initialize 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>'}]
    });
// render initialized dashboardlayout
dashboard.appendTo('#dashboard_default');

var 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>';

var toggleBtn = new ej.buttons.Button({
  cssClass: "e-flat e-primary e-outline",
  content: "Enable Floating",
  isToggle: true
});

toggleBtn.appendTo("#toggle");

document.getElementById('toggle').onclick = function() {
    var panels = [];
    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;
    }
};
