Flex drag and drop

Hi Forum,

i’m new to flex.

I want to make a form manager where a user can drag components on to a blank area, but i want it to work like a tile list.

So the components are in the tile list and it moves them down if a new one is drop in the middle for example. Can you put components such as text boxs and drop downs in a tile list? Or would i have to use the drag and drop class manually and perform collision detection and move everything manually?

Any help would be appreciated.
