I was messing around with the PDL Editor in Hubzilla, trying to add some custom navigation that does not depend on themes.
The documentation at
https://hubzilla.org/help/Widgets needs more information.
For example,
random_block - display a random block element from your webpage design tools collection. Permissions are honoured.
args:
contains - only return blocks which include the contains string in the block name
channel_id - if not your own
would need to look like:
[widget=random_block][var=contains]menu[/var][/widget]
If you want to show the block called menu.
This post is just a note to myself that this needs to be communicated in the documentation somehow.
