Customize the Menu

By default, the slide-out menu is empty. To specify its content, declare a template for it. Although the slide-out menu can contain any widget, we recommend you place a collection widget there. For example, in the following code, the slide-out menu contains the TreeView widget. Note that this widget is placed into a dxTemplate whose name is assigned to the menuTemplate option of the SlideOutView. All the other code configures the TreeView and does not affect the SlideOutView directly.

<div id="slideOutView">
    <div data-options="dxTemplate: { name: 'content' }">
        <div id="toolbar"></div>
        <div id="chart"></div>
    </div>
    <div data-options="dxTemplate: { name: 'treeView' }">
        <div id="treeView"></div>
    </div>
</div>
$(function() {
    var slideOutView = $("#slideOutView").dxSlideOutView({
        menuTemplate: 'treeView',
        contentTemplate: 'content'
    }).dxSlideOutView("instance");

    var toolbar = $("#toolbar").dxToolbar({
        // Toolbar is configured in the "Customize the View" article
    }).dxToolbar("instance");

    var chart = $("#chart").dxChart({
        // Chart is configured in the "Customize the View" article
    }).dxChart("instance");

    $("#treeView").dxTreeView({
        width: 200,
        selectionMode: "single",
        selectByClick: true,
        onContentReady: function (e) {
            e.component.selectItem("1_1");
        },
        dataSource: [{
            id: '1',
            text: 'Fruits',
            expanded: true,
            items: [
                { id: '1_1', text: 'Apples', china: 37001601, usa: 4110050 , turkey: 2889000 },
                { id: '1_2', text: 'Oranges', china: 14400000, usa: 15700000, turkey: 1800000 }
            ]
        }, {
            id: '2',
            text: 'Vegetables',
            expanded: true,
            items: [
                { id: '2_1', text: 'Cucumbers', china: 54300000, usa: 886480, turkey: 1800000 },
                { id: '2_2', text: 'Tomatoes', china: 33911935, usa: 10965452, turkey: 5976732 }
            ]
        }],
        onItemSelectionChanged: function (e) {
            if(e.node.children.length < 1) {
                slideOutView.hideMenu();
                var toolbarItems = toolbar.option("dataSource");
                toolbarItems[1].text = e.node.itemData.text;
                toolbar.option("dataSource", toolbarItems);
                chart.option("dataSource", [e.node.itemData]);
            }
        }
    });
});
#slideOutView {
    height: auto;
    position: absolute;
    top: 0; 
    bottom: 0;
    width: 100%;
}

The menuTemplate option can also accept a function combining the HTML markup. In this case, you do not need to specify any markup for the slide-out menu in the HTML file.

HTML
JavaScript
<div id="slideOutView">
    <div data-options="dxTemplate: { name: 'content' }">
        <div id="toolbar"></div>
        <div id="chart"></div>
    </div>
</div>
$(function() {
    var slideOutView = $("#slideOutView").dxSlideOutView({
        menuTemplate: function (menu) {
            menu.append(
                $("<div />").attr("id", "treeView")
            )
        },
        contentTemplate: 'content'
    }).dxSlideOutView("instance");

    // The rest is omitted for brevity
});

By default, the menu slides out from the left side of the screen. To make it slide out from the right side, change the menuPosition option.

JavaScript
$(function() {
    var slideOutView = $("#slideOutView").dxSlideOutView({
        menuTemplate: 'treeView',
        contentTemplate: 'content',
        menuPosition: 'inverted' // or "normal"
    }).dxSlideOutView("instance");

    // ...
});

In addition, you can use a 3rd-party template engine to customize the menu. For more information, see the Use an Alternative Template Engine article.
