Im working with the autocomplete inside of a dialog. the autocomplete positioned in the middle\bottom of the dialog.
When i get the select menu results, the dialog gets a scroll because of the select menu height (to see the result i need to scroll the dialog), in a result i had to limit my result, and change the height property of the dialog.

I think that:
The select menu should go over the dialog tough its inside the dialog body div.
        or
Add a scroll to the menu by calculating the extra space and position it on top or bottom.
