I've been searching around and trying various old options, but I can't seem
to find exactly what I need, so I'm asking directly. Is there a way to have
an expandable tree generated, like the TOC example here:
http://tiddlywiki.com/#TableOfContents
But I don't want to have to specify which tiddlers should appear in the
TOC. I would like to do it by specifying a root tiddler, and then all the
child tiddlers would have a field called "parent", which would point to the
root tiddler.
In this way, you could have multiple levels, with each pointing to the
relevant parent:
* Root (no parent)
* Level 1 (parent="Root")
* Level 2 (parent="Level 1")
Then later on I could add another tiddler "New", give it the parent "Root",
and the TOC would appear like this:
* Root (no parent)
* Level 1 (parent="Root")
* Level 2 (parent="Level 1")
* New (parent="Root")
So the macro call would be:
<<TOCtree root="Root">>
The advantage of using the field like that is that I would only need to add
the field to a tiddler, and the TOC would update.
Also, by specifying the root of the tree in the macro call, I could just
show branches instead of the whole thing.
Is this possible? Has it been done?
