I would like to output FM files using Responsive HTML5, but without the header bar or TOC/navigation. Essentially, I want what I get with Basic HTML output in terms of the index and separate (not linked) HTML files, but still keep the Responsive HTML5. Is that possible?
What version of FM are you using? IIRC there was a newer HTML output format created recently (last few years) that was sort of like the old Basic HTML export but using HTML5, but I forget what it was called.
Ah, maybe the "Basic HTML" one was what I was thinking of - that would have replaced the old Save As HTML one.
If you right click on TOC file in the left-hand Frame navigation and select "Exclude," when you generate the HTML5 content your HTML output's left hand navigation will substitute the file names of the files in the book for the TOC navigation links. It doesn't eliminate the navigation pane, but it does remove the TOC element.
