filterLabel String

When filtering is enabled, allows aria-label to be defined for the filter input element.

Example - set the filter label

<input id="ddt" />
<script>
    $("#ddt").kendoDropDownTree({
        dataSource: [
            { text: "Chai", value: 1 },
            { text: "Chang", value: 2 },
            { text: "Tofu", value: 3 }
        ],
        filter: "contains",
        filterLabel: "custom title"
    });
</script>
