I have a mb_frontend_form for creating a custom post. One of the fields for the post is a hierarchical taxonomy with about 100 terms. I can't find a nice way to make this easy for the users. If I set field type to Select, Select Advanced, or Checkbox List, terms are not displayed in a hierarchy. Select Tree for some reason shows only parent terms, not children. Checkbox list works, but with a lot of terms it overwhelms the rest of the input form.
What I would like is an accordion tree view with checkboxes, so the user can browse through a compact representation of the term hierarchy and select terms conveniently.
Maybe I could create a metabox with a Select, Checkbox List, or maybe Select Advanced field, with 'flatten' => false??
Or perhaps create a new field type that does everything beautifully? There's some good jquery out there.
Please advise. I'm hoping this is easy. Thanks.
