I have a pageframe which contains a few dozen checkboxes, grouped together in related 'columns' or areas of the page. Something like the following, but with varying #s of options in a couple different groups.

Option A
Option B
Option C
Option D
Option E
Option F
Option G

Another administrator option allows users to hide selected checkboxes on the pageframe referenced above, by the form's INIT or the object's REFRESH. So Option B, D and F, for example, could be "turned off" or hidden.

Can anyone suggest an elegant, non-brute force way of conditionally setting the TOP of a given object based on the VISIBLE setting of each object? Such that the visible objects are vertically aligned next to each other, without gaps from the non-visible objects.
