Im using contact form 7 plus Easy FancyBox to display the forms in pop up windows in GeneratePress,
but I’m not able to make it work properly when the form is launched from a Menu item: either the popup opens a new window with the form and the whole web in it rather than only the form, or it goes to another page or directly nothing happens)
and it works great but I’m not able to add this to a Menu element.
I’ve tried with shortcodes in menus but the thing is I cannot add html to menu elements …
You might need to ask the plugin author if it’s possible with their script. They might have an idea/specific instructions that will work with their plugin.
