I have created a biology textbook in ID, with fully-operative Flash animations, MSO's, and all those other good things. But -- it contains many chapters and many sub-sections within the chapters. The "multi-level TOC" option produces a drop-down TOC that takes eons to scroll through. How can I make it collapsible, so that the chapter titles alone appear in the main list, and the sub-sections open up only after the chapter title has been clicked? I have some knowledge of unzipping the epub and editing the xhtml, which I must to do insert the Flash animations, and to find the text boxes whose right or bottom borders fail to show up (so I can fix them in AI), but I do not know how to proceed when editing the TOC to make the collapse/expand function workable. Nor do I find an obvious way to ask ID to set it up this way, which I would have thought would be "obvious" to the ID developers. Any thoughts?
Are you not limiting the number of users by using Flash animations?
