Floating panels in ASP.NET MVC Dashboard Layout control

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 using allowFloating property.

@model WebApplication.Controllers.HomeController.spacingModel

    <!--  Button element declaration -->
    @Html.EJS().Button("toggle").Content("Enable Floating").CssClass("e-flat e-primary e-outline").IsToggle(true).Render()
    <!-- end of button element -->
<div class="control-section" style="padding-top: 15px;">
        <!--  DashboardLayout element declaration -->
        @Html.EJS().DashboardLayout("dashboard_default").Columns(6).AllowFloating(false).CellSpacing(Model.cellSpacing).Panels(Panel =>
            Panel.SizeX(2).SizeY(2).Row(1).Col(0).Content("<div class='content'>0</div>").Add();
            Panel.SizeX(2).SizeY(2).Row(2).Col(2).Content("<div class='content'>1</div>").Add();
            Panel.SizeX(2).SizeY(2).Row(3).Col(4).Content("<div class='content'>2</div>").Add();
        <!-- end of dashboardlayout element -->

    document.addEventListener('DOMContentLoaded', function () {
        // Create instances for dashboardlayout
        var dashboard = document.getElementById('dashboard_default').ej2_instances[0];
        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>';
        // Toggle button to enable and disable floating
        document.getElementById('toggle').onclick = function (e) {
            var toggleBtn = document.getElementById('toggle').ej2_instances[0];
            let 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;

    /* DashboardLayout element styles  */
    #dashboard_default .e-panel .e-panel-container .content {
        vertical-align: middle;
        font-weight: 600;
        font-size: 20px;
        text-align: center;
        line-height: 90px;

namespace WebApplication.Controllers
    public class HomeController : Controller
        public class spacingModel
            public double[] cellSpacing { get; set; }
        public ActionResult Index()
            spacingModel modelValue = new spacingModel();
            modelValue.cellSpacing = new double[] { 10, 10 };
            return View(modelValue);

When allowFloating value set as false, the output is like the below.

When allowFloating value set as true, the output is like the below.
