I have some questions about drop down menu. will you plz help me?!
1- Should I use a combo-box to create a drop down menu?
if so, how can I make it some how readonly? I mean, I dont want the user to be able to write new things. For example, Just if he/she enters 'a' all of the items which start with 'a', appear.
2- In a drop down menu the user can scroll the list by both mouse and arrow keys.
I want to send the selected item to another function at the select time but I dont know which event to use?!
By selected item I mean, the one which is clicked on while using mouse and the one which the user presses the enter key when he/she gets to it (while using arrow keys).
