A to Z taxonomy plugins
We’ve been developing oik-a2z and oik-shortcodes-a2z to provide A to Z taxonomy selections.
oik-a2z provides a taxonomy called letters, label “Letters” that simply associates the post to a particular letter.
oik-shortcodes-a2z provides a taxonomy called oik_letters, label “API Letters”, that associated the post to a range of letters.
The terms are automatically set each time the post is saved.
