>I have worked with scroll containers before adding text boxes and all worked well. I recently tried to add one which contains a list of options (an optiongroup) . This does not work. When I click on options within, the scroll container jumps up or down in the list and doesn't even select the option I clicked on. Does anyone know why an option group would behave this way in a scroll container? Is there a way to correct this?

Which scroll container class you're using? By Carlos Alloatti?
