iconUrlTemplate

The template string or function for determining the TreeView node's icon URL. This URL must point to an 16x16 image, otherwise custom styling of the control will be required.

<script type="text/javascript">
    jQuery(function ($) {
        $("#treeview").shieldTreeView({
            dataSource: {
                data: [
                    { text: "Item One",  iconUrl: "/img/one.png" },
                    { text: "Item Two", iconUrl: "/img/two.png" }
                ]
            },
            iconUrlTemplate: "{iconUrl}"
        });
    });
</script>
