I want to use conditional logic to actually remove/empty/disable a field, rather than just hide it from view. I notice that if you enter a value in the field and it is hidden later with CL, it still saves in the meta database.
My current scenario for needing this (among others) is with address entries. 99% of the addresses are US-based, so I have a select box with the US States. However, if another country is selected, CL will hide the select box, and show a text field for text entry. The issue is that I have both fields saved, so if I were to select a state, then change the country, I can potentially have two fields for the State (or Province/Region)
How can I disable or empty one field if it is hidden with CL?
