ignoreCase Boolean(default: true)

If set to false case-sensitive search will be performed to find suggestions. The widget performs case-insensitive searching by default.

Example - disable case-insensitive suggestions

<input id="dropdowntree" />

<script>
    $("#dropdowntree").kendoDropDownTree({
        dataSource: [{ text: "a-item1", value: 1 }, { text: "A-item2", value: 2 }],
        filter: "startswith",
        ignoreCase: true
    });
</script>
