Validation on MultiSelect

[Oscar]

How can I use validation on a MultiSelect when using PHP wrappers to render the control? I know with HTML you can use the attribute "required" on the "select" tag but how is this done using PHP wrappers?

Never mind. Found the attr function for the Widget few seconds after posting this question.

If someone else is looking for the same:

$multiSelect = new \Kendo\UI\MultiSelect("multiSelect");
$multiSelect->attr('required', true)
