David, It was not obvious to me what Tony & Jeremy meant by "using a template parameter" as I was not aware of how it is used!
If you look on the last line on the documentation for Table-of-Contents Macros <https://tiddlywiki.com/#Table-of-Contents%20Macros>, it says: *template* Optionally, the title of a tiddler to use as a template > <https://tiddlywiki.com/#TemplateTiddlers> for transcluding the selected > tiddler into the right-hand panel So the correct way is to create a template tiddler, say named : *CustomTocTemplate* Put the following in that tiddler: <h1><<toc-caption>></h1> <$transclude mode="block">$missingText$</$transclude> Then when you define your Table if Contents, you do it similar to this: <$macrocall $name="toc-tabbed-internal-nav" tag="TableOfContents" *template="CustomTocTemplate"* selectedTiddler="$:/temp/toc/selectedTiddler" unselectedText="<p>Select a topic in the table of contents. Click the arrow to expand a topic.</p>" missingText="<p>Missing tiddler.</p>" /> Don't forget to undo the changes you made earlier by simply deleting the edited shadow tiddler : *$:/core/macros/toc* Apologies for the earlier not so hot quick fix! -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
