Hey Anh - bumping this old topic, hope you see.
I too would like to use the taxonomy slug in the Taxonomy select field.
My purpose is in a custom search form using MB fields. WP doesn't seem to search term IDs passed along by URL.
- Any suggested way to do this?
- If I could add
data-slug attributes to the taxonomy <option> elements, that would also help (instead of changing the option value)
