Drag & Drop Custom Sections of HTML ("Include" / "iframe" kinda)
I'm looking to create custom sections of code to have placed on various landing pages — kind of like you can insert a form on a page as a "container".
For the technically inclined, I'm essentially looking to do an "include", in a way. There is a standard section of HTML that I want to be able to drag and drop onto a landing page and want to be able to drop multiple sections underneath each other, if possible.
Any help?
