I've been searching high and low all day and night and cannot get this simple feature to work as I'm a bit rusty at this javascript,

Here is what I'm trying to accomplish below: 

http://jsfiddle.net/dimerbox/5aQJQ/1/

I would like to link the Option Select Dropdown to sort instead of just Li's, if this isn't possible should I just get an li dropdown menu to complete this effect?

I assume it's something to do with the this function 

2. $(function(){
3. $('#Grid').mixitup();
4. });

Thanks all for your help,

Daryl
