BTC, thanks for the help. I really like the solution with tge “contains” operator but will wait for this to make it into the release version.
In the meantime, I’m fine with having a category tree with only one parent. However, your code doesn’t quite give the correct result, yet. When calling <<class_sub>> on its own it returns only the current Tiddler with “[[“ added to the tiddler name (as part of the link) and “]]” added afterwards (in plain text). The list-links filter in the wikify portion is consequently empty. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
