I saw a template in the GP Premium Site Library that had some features I wanted for my site. (GP Premium is such a great starting point for an otherwise blank page!) I didn’t want to import the whole template because it would overwrite my design, so I imported it into a different site and then copied and pasted the blocks I wanted.
The design copied over, but certain functions didn’t. Specifically, the right sidebar didn’t stay in position on my site like it did in the Site Library template. Here’s a screencast showing what I mean:

How can I enable this function?
