Limit selected options

How I can limit the select options, either the Right side or Left side?

Hi, I think you can achieve this by using the beforeMoveRight / beforeMoveLeft callbacks.

a very simple code didn't work: beforeMoveToRight: function($left, $right, $options) { alert($options); return true; }, any suggestions?

I needed to limit the amount of options being move to the $left column. This worked for me:

beforeMoveToLeft: function($left, $right, $options) { if($left.children('option').length >= 2) { return false; } else { return true; }; }

Also $options is an object. Putting it in an alert will only tell you [Object object]. console.log($options); will show you what's in the object.

Hope it helps.
