Is it possible to use the category field to select the parent category and then have a field to add your own child category when submitting the forum?
So something like this
If a parents selected display a field to enter a new child category. but if a child category is selected dont display a field to enter anew category?
Sadly i have no code as im unsure if this is even possible.
This isn’t possible with the existing conditional logic, however, it could be built using what is available.
Instead of using a taxonomy field for the “Parent” category, or depending on the “Category” box, you can use a select field and then dynamically fill the select field with only top level terms. http://www.advancedcustomfields.com/resources/dynamically-populate-a-select-fields-choices/
Allow your select field to have a null value and then display the text field to enter a child field if the select field value is empty.
Then create an acf/save_post filter that adds the category and adds the term to the post: http://www.advancedcustomfields.com/resources/acfsave_post/
I’m sure there will be a lot of little things that you also need to deal with that I haven’t thought about.
You could also include a radio button that asks “Add new sub-cagegory?” and if the user selects yes then show the “Parent” category select field and the text box for adding the sub-category.
