But, on a post… how does that populate list “b” when the value of list “a” changes, and how, if both list “a” and list “b” are taxonomies (Type and Reporting Category) does the select list for reporting category (on the custom post) get filtered to only show reporting categories associated with the selected “type”?
I’ve done this literally hundreds of times over the years in various languages, I’m finding it a nightmare in WordPress given the insane way a Select input is constructed.
Hi
Did you get an answer to this? I’m looking to do similar, i.e. select a “Type” and then refresh the options for a “Reporting Category” select without doing a page refresh. I can do this in minutes with javascript and standard select inputs, but these wordpress selects are insane…
Cheers
