[Looking for] A visual composer add-on that can drag a set of element

Hello, around 2-3 months ago I think I’ve found a nice plugin that is a Visual Composer Addon but I can’t remember its name.

It’s has features like in this link:

which can drag and drop set of elements into a page, not a single element like in normal Visual Composer.

Please help me suggest its name, really wanna buy it.
