Jquery modal popup to select form values

Hi I wonder if anyone can help. I have a form with an number of quite long drop down select menus in table rows.

The problem is if the user selects one of the last options in the select menu they are taken to the a different row lower down on the form - which is a little confusing.

What i really need to do is present some the values in a popup modal box and then allow the user to pick a value and keep them in that input field. It would be a lot like the jquery date picker jQuery UI - Datepicker Demos & Documentation but with numbers like 0,1,2,5,10,15,20 ect to pick from and populate the input field.

I am a bit short of time so i was wondering if anyone knew how to do this quickly - surely its a problem others have come across?

Thanks for your help

Have a quick look at the chosen plugin. Could that be made to work?

Check the dialog() of the jquery UI, it allows to fill in forms inside modal popus.
