I want to create a TOC for my responsive HTML5 output in which the TOC defaults to already being expanded.
Instead of this . . .
. . . we want this to be the default.
Can this be done?
The short answer is No.
Different skins have different behaviours and in some a book will stay open once the user expands it. However, that is not what you want.
There are many threads already on this. Search on Expanding TOC.
Thank you for the quick response, Peter.
Not the answer I wanted to hear, but the one I expected nonetheless.
