You need to add the multiple flag to your select tag. Like this:

All of the items selected will be passed as an array to your script. So the cgi param collab will be an array, with each slice being one of the values selected from the menu. Also of note, by adding the multiple tag, your html will be rendered as a box, not as a drop down menu.
