Solution
Depending on the TreeView rendering and styling options that you use, apply either the solution for the new rendering or the old rendering.
New Rendering
The following example demonstrates how to achieve the desired scenario.
<div id="treeview"></div>
<script>
$("#treeview").kendoTreeView({
dataSource: [
{ text: "Furniture", items: [
{ text: "Tables & Chairs" },
{ text: "Sofas" },
{ text: "Occasional Furniture" }
] },
{ text: "Decor", items: [
{ text: "Bed Linen" },
{ text: "Curtains & Blinds" },
{ text: "Carpets" }
] }
]
});
</script>
<style>
body {
font-size: 12px;
}
.k-treeview .k-treeview-top,
.k-treeview .k-treeview-mid,
.k-treeview .k-treeview-bot {
background-image: url('https://d35islomi5rx1v.cloudfront.net/mvc/2012.2.607/Default/treeview-nodes.png');
background-repeat: no-repeat;
margin-left: -16px;
padding-left: 16px;
}
.k-treeview .k-treeview-item { background-image: url('https://d35islomi5rx1v.cloudfront.net/mvc/2012.2.607/Default/treeview-line.png'); }
.k-treeview .k-treeview-last { background-image: none; }
.k-treeview .k-treeview-top { background-position: -91px 0; }
.k-treeview .k-treeview-bot { background-position: -69px -22px; }
.k-treeview .k-treeview-mid { background-position: -47px -44px; }
.k-treeview .k-treeview-last .k-treeview-top { background-position: -25px -66px; }
.k-treeview .k-treeview-group .k-treeview-last .k-treeview-bot { background-position: -69px -22px; }
.k-treeview .k-treeview-item {
background-repeat: no-repeat;
}
.k-treeview .k-treeview-first {
background-repeat: no-repeat;
background-position: 0 16px;
}
</style>
