As a developer, I want to use conditions across field groups in the admin so that I can better organize my fields.
Conditions for entire field group display or conditional logic for field display?
Conditional logic for field display based on a field in another field group can be accomplished by using an acf/prepare_field filter and modifying $field['conditional_logic']. This is an array with field keys, operators and values. You can see an example or how to set up this array by creating a field that is similar to what you want and then exporting it to PHP.
