Conditional logic is a container that lets you apply rules based on the value of fields in order to hide part of it, streamlining the user interface.
Conditional logique is only available in the pro versions of Modern Fields.
Configuration
First, go to Modern Fields > Fields groups and add the conditonal logic block. It’s a container where you can fit multiple fields inside.
You can define one or more combined rules to control the display of the container.
The rules only apply for the fields outside the container. You can set rules based on boolean, numeric and text values.
Usage
In the post displaying your field group, the conditional container will be hidden until the conditions are met.
If several rules are active, they must all be valid for the fields to appear.
Get values from a conditional container
The conditional container has no impact on retrieving values on the front-end.
You can still use the usual the_field() and get_field() functions.
