The dxResponsiveBox widget enables you to position layout elements depending on the current screen size. This widget is useful if you need to create a site with different layouts for different devices (phone, tablet, desktop).

You can create a widget using one of the following approaches.

  • jQuery
    Use the dxResponsiveBox jQuery plug-in.

    HTML
    <div id="responsiveBox">
        <div class="header" data-options="dxItem: { 
            location: [
                { row: 0, col: 0, colspan: 3, screen: 'lg'},
                { row: 0, col: 0, colspan: 2, screen: 'xs sm md'}
            ]
        }"> . . . </div>
        <div class="content" data-options="dxItem: { 
            location: [
                { row: 1, col: 1, screen: 'lg' },
                { row: 1, col: 0, colspan: 2, screen: 'xs sm md' }
            ]
        }"> . . . </div>
        <div class="left-side-bar" data-options="dxItem: { 
            location: [
                { row: 1, col: 0, screen: 'lg' },
                { row: 2, col: 0, screen: 'xs sm md' }
            ]
        }"> . . . </div>
        <div class="right-side-bar" data-options="dxItem: { 
            location: [
                { row: 1, col: 2, screen: 'lg' },
                { row: 2, col: 1, screen: 'xs sm md' }
            ]
        }"> . . . </div>

    $("#responsiveBox").dxResponsiveBox({
        singleColumnScreen: 'xs',
        rows: [
            { ratio: 1 },
            { ratio: 2 },
            { ratio: 2, screen: 'sm md' },
            { ratio: 1 }
        ],
        cols: [
            { ratio: 1 },
            { ratio: 2, screen: 'lg' },

        singleColumnScreen: 'xs',
        rows: [
            { ratio: 1 },
