Here I talk about integration of snippetmaster:would appreciate if you could create a little workshop kind of thing especially dealing with snippetmaster
Once installed (see instruction in snippetmaster site), in DFM is sufficient to add the following tags before and after the editable text:
<!-- #BeginSnippet name="name" --> your yext <!-- #EndSnippet -->
and the text is editable in the backend. The use in dfm is the same as any html website.
More powerful is FusionNews, that let you create new contents divided by categories (in the official site there's the user guide) or, as Rommel suggested, "WebsYep". But there are a lot of external scripts to edit html content from the backend, the only problem is having the auto-fit page to accomodate dynamic content, as Rommel (and me) asked avoiding the use of internal scrollbars.
