To add popups
In the left panel, click Pages, and then click the Popups tab.
Click + New Popup.
Select a popup type. The popup type pre-populates the popup with widgets.
Type a name for your popup, and click + Add Popup.
Activate Popups
Unlike a page generated in the navigation automatically, a popup can only be triggered by being clicked as a link - see below!
Link to a Popup
There are several widgets that allow you to link to a popup, such as Photo Gallery image links, text, and buttons.
To link to a popup:
Right-click the widget that you want to link to the popup from, then select Edit content. Alternatively, if you are linking from text, highlight the desired text and click the link icon in the text editing menu.
Click Popup, then select which popup you want to link to from the dropdown menu.
