I've implemented Heirachy to create categories within categories tree. I'm wondering
a) if there's a simple way to create a page where users can create and drag n drop categories like the SiteTree functions.
b) if I can modify ModelAdmin so when I manage 'Categories' dataobject (select the Categories tab in ModelAdmin) it shows a CategoryTree and details page, like SiteTree does. I.e. override default ModelAdmin left and main panels.
Cheers!
