We have a very long pop-up menu list in a portal so it will be very useful (if not necessary) to be able to type the first letter of the value that we want to enter to broswe through that very long list.
I know that we can not do it in a pop-up menu but drop-down list allow it. Drop-down list will only show the first field (ID) and not the second field (name) of the value list. To fix that I used the trick to put a pop-up menu over a drop-down list and it's perfect.
My problem is I can not used that trick inside a portal.
