Hi all

I have a page with multiple small regions in columns, for example

Region 1 (Automatic column start, Automatic span) - this is IG

Region 2 (Automatic column start, 2 Column Span) - this is Static

Region 3 (Starts column 9, 4 Column Span) - this is IG

The users want to show/hide Region 2 and Region 1 fill its space (expand into the space) leaving Region 3 where it is.

I have the show/hide working but how do I get region 1 to refresh/re-draw or expand to fill the span of the columns or to move Region 3 back to column 9?

Screens below

After "Show Action" (Region 1)

After "Hide" (Region 2)

Thanks in advance
