headerTemplate String|Function

Specifies a static HTML content, which will be rendered as a header of the popup element.

Important The header content should be wrapped with a HTML tag if it contains more than one element. This is applicable also when header content is just a string/text.

Important Widget does not pass a model data to the header template. Use this option only with static HTML.

Example - specify headerTemplate as a string

<input id="dropdowntree">
<script>
$("#dropdowntree").kendoDropDownTree({
  dataSource: [
    { id: 1, name: "Apples" },
    { id: 2, name: "Oranges" }
  ],
  dataTextField: "name",
  dataValueField: "id",
  headerTemplate: '<div><h2>Fruits</h2></div>'
});
</script>
