You can set conditions individually for each field, but it can become challenging to maintain if you want to hide an entire group of questions. Instead of applying conditional settings to each field, you can set the conditions on the first field in the section and enable the Apply conditions for this field to the entire section toggle. This way, the conditions will apply to the entire section, making it more manageable.
Conditions can also be stacked, where the section has certain conditions and fields within it have others. The section itself will then only be visible when the header field's conditions are met, but each field within the section will only show when its conditions have been met as well!
Conditional Pages
This option also automatically applies to pages if the multi-page mode is enabled.
