I figured it out. Even though the documentation doesn't explicitly say so, the toc macros do support a sort input. In my case I added a field called order which I populated with the correct numerical order for each book. Then I made my Contents tiddler say:
<$macrocall $name="toc-tabbed-internal-nav" tag="Book" sort="nsort[order]" selectedTiddler="$:/temp/toc/selectedTiddler" unselectedText="<p>Select a book in the table of contents. Click the arrow to expand a topic.</p>" missingText="<p>Missing tiddler.</p>" /> And that did it. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
