Triggering a popup from a nav menu item is easy to do.
Create the Popup
First, create your popup.In the Advanced tab of the Popup Settings, we will add a small code snippet into the Open By Selector field. For this example, we’ll enter the code shown below.a[href=”#popup-menu-anchor”]Now publish the popup and set the Display Conditions. If the menu is in a site wide header, set the Display Conditions to Entire Site. If the menu is on a specific page, set the Display Conditions to that specific page (Singular > Pages > search and select your page).Ensure that no Triggers or Advanced Rules are set for your popup.
Note: Make sure that straight quotes are used and not curly quotes to avoid jQuery errors.
