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

• "small"
• "medium"
• "large"
• "full"

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

Example - sets the roundness

<input id="otpinput" />
<script>
    $("#otpinput").kendoOTPInput({
        items: 3,
        rounded: "full"
    });
</script>
