I am using Sectiontoggle and it works well. The related 'Edit' button displays against sections up to Heading 3. Can I force it to display an edit button for Section4?
in "Configuration Settings" set the "Maximum section edit level" to 4. I think that solves your problem.
Of Course! How stupid I was looking in the Editing section and I checked SectionToggle because I thought perhaps it did it. I didn't think to look in Display section!
