So should the letters that don't have articles show but bu 'unlinked' (so plain text)? Or not show at all?
Should they link to a page that has all the articles that begin with that letter?
Or link to an anchor just above the first article with that letter, on the same page that shows all articles?
It is doable, but a LOT of code. If I would make it myself, I'd probably write custom PHP to grab the data from the database and output it all.
Anyway, you would need to have an {articles} tag for EVERY letter in the index. AND for every letter in the list.
So that is 52 {articles} tags per list.
Or alternatively, output 26 {articles} tags for the list, and use Quick Index to generate an index above it (which would then only show the letters that are available.
If you think you still want to use Articles Anywhere to create this, I can show you how. But again, I'd use a different approach myself.
I wasn't planning on using Articles Anywhere to create the Index itself but rather wondering if that could be an option. That list I shared will grow bigger and bigger and filtering based on Alphabet Bar.
However, if I create a glossary and using AA to group based on alphabet, how do I get AA to the first letter of a custom field (I have a custom field that I put the sort version of the name)?
