Sets a value controlling size of the component. When undefined (the default), the theme controls the default size. Can also be set to the following string values:

• "small"
• "medium"
• "large"

The "none" value is deprecated. Use custom CSS instead.

Example - set the size

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