I'm rewriting some existing apps using GWT and I've come across a GUI issue. In many cases where I have used a select element as a pull down menu (only 1 item visible at a time), I leave the first item empty and disabled. The user has to choose a different option and he/ she cannot go back to the empty element. Using a ListBox, it's easy enough to leave the first element (index 0) empty. But how do I disable that first element so that it can't be selected?
