I want to allow an editor to be able to add multiple macros to an area on my page. One after the other.

So it would be something like the editor would select a macro which they would populate and then insert into the page. The macro is a section of html containing an image and underneath that some descriptive text. It is a square and the right size to allow 3 columns on a page.

Then they would have an option to do the same again and again if they want to. The html and css will take care of the layout.

How can this be done. Is there a built in document type property that would allow this?

Thanks.
