I have a multiple choice column of potential attendees that are to be enrolled in a course. After the number of available spots is filled, I disable the column along with the "Add" button, yet one problem remains.
When I open the page, the first option appears to be selected. If I double-click on the selection area, that first option, the potential attendee is put on the attendee's list to the right. I have searched this topic quite a bit and no solution worked so far.
