Clicking on the "click" property will open a drop-down with the "Target Type" options available for the element when you click on it.
Nothing will happen when the element is clicked on.
Clicking on the "Page" option will display a drop-down selector showing all user pages available to be linked to.
Clicking on the "Special Page" option will display a drop-down selector showing all "System" pages available to be linked to.
Clicking on the "Web Address" option will display a text field to enter the URL of a website with a checkbox below to enable the link to be opened in a new browser tab.
Clicking on "Visibility" will open the property field. By default, this field is empty.
To use the Visibility property you will need to enter an appropriate code-base variable reference.
Using the Visibility property is for advanced use of the editor and should be carefully considered and documented as needed accordingly.
