Hey there, it sounds to me like you need to be using JavaScript for this. Have a look at something like this: https://stackoverflow.com/questions/30232146/dynamically-populating-drop-down-list-from-selection-of-another-drop-down-value
👍🏼

Thank you so much, I got a fix that works perfectly here: https://bdwm.be/how-to-create-dynamically-populated-cascading-dropdown-lists-for-contact-form-7/

I will however suggest, for future reference to anyone, to check the comments, there were some mistakes in the code that were corrected in the comment session.

Again, thanks for your help and the timely response.
