ACF Supported Selecting multiple taxonomies within a taxonomy

Hello,

I recently purchased a theme called themes. This theme includes several taxonomies. For example, it has two taxonomies: “Services” and “Specialities.”

The “Specialities” taxonomy lists medical specialties, such as cardiology and cardiovascular surgery.

The “Services” taxonomy lists services provided, such as “pacemaker implantation.”

When adding a new taxonomy in the “Services” taxonomy, there’s a “Select Specialty” section. So, when adding a taxonomy called “Pacemaker Implantation,” we can select the “Cardiology” section. However, multiple selections are not possible.

When selecting the “Pacemaker Implantation” service, I want to associate it with multiple specialties, such as “Cardiology” and “Cardiovascular Surgery.”

How can I do this? Thank you.
