I tried to modify the registration fields and ran into some trouble.
First, I tried to add a multi-select field (Type:Drop Down (Multi-Select)). I entered the field type, added all the values and chose size as 20 (not sure if this was the height of the multiselect or the width).
When I went to the registration page, the multiselect box appeared ... but it was only 1 row high ... so the user couldnt scroll any lower and multi-selecting was near impossible.
Any idea how to fix this?
