Visibility rules
Visibility rules decide whether a block appears on the published page. Show a notice only when a field has a value, hide a button for logged-out visitors, or show a banner only in the morning.
Rules work on every block, including blocks that can't take a dynamic tag, and they're checked each time the page is displayed. In the editor, blocks stay visible so you can keep designing. See Adding visibility rules.
Visibility rules are different from conditional logic: conditional logic hides fields on the editing form; visibility rules hide blocks on the public page.
