Display or hide your field's content based on a variable from the URL
This restriction plugin lets you choose to display or hide your field's content based on a variable from the URL. For example, you can use this field to hide your field's content on a page with a particular article ID, within a particular category, on a page with a certain menu ID, and so on.
Beside matching mode "isEqual", there is also an option "isFilled" where field will be shown (or not if Inverted is chosen) when variable has any value
Note: this extension is included in all SEBLOD Core packages, starting with SEBLOD 3.8.0
