Hi Long,
No worries, and thank you for taking the time to do the video.
I CAN already get the plugin to do the functionality you are showing, however, that is not the question I am asking.
In your example, I would like to be able to add MULTIPLE, differently designed sections to a page and be able to sort them. In you example and the YouTube video, they are only using a single design and group.
I've done you another very short video, using your example to hopefully try to better explain what I am trying to do with the plug-in.
Here is the link to the video - LINK - and again, thank you for your patience.
