Alligator Menu Popup


This is a fork of my similarly named Alligator Popup Plugin. Unlike the original plugin, this one enables you to open the target of a menu item of your WordPress custom menu in a popup window.

Add the ‘mpopup’ class to a menu item in a custom menu to open the target in a popup Window.

Enables you to specify that a menu item on your WordPress custom menu will open in a new popup window. An admin page allows you can control the size of the popup window and whether it has scrollbars.


You will find the Menu Popup Settings Page at Settings => Menu Popup

  • Set the dimensions of the popup window and whether you want the popup window to be scrollable

Then edit your custom menu at Appearance => Menus
* Enable the CSS Classes option in the Screen Options pull-down panel on the menu editor page.

  • Add the mpopup class to any menu item where you want the target page to open in a popup window.

When the menu item is clicked, the link should now open in a popup window.

Install the same as any other plugin


Where is the admin page?

You’ll find it at settings => Menu Popup

How can I add the mpopup class to my menu item?

If your menu item editor is not showing the ‘CSS Classes’ field, you can enable this by going into ‘screen options’ and selecting the ‘CSS Classes’ checkbox.

How do I get a link to popup if it is not a menu item?

You can use my Alligator Popup plugin for that

Why doesn’t it work for me?

It works for me, but all sites are different. Post a support request and I’ll try to help you get it working

You know when a plugin is easy to find, easy to understand, doesn’t mess up your site and is FREE? Yeah – me neither. This is that plugin. Thank you for being a unicorn. This plugin ROCKS!!!!

Lately when you search for popups it’s all lightbox which is in fact not a popup but an overlayer with z-index, which is very misleading. This plugin understands the definition of a popup and makes it true. Thank you!

Installed it, set dimensions of window in settings, but then what? Went to menu, nothing extra there. Couldn’t see instructions for next step or new features in menu items. Then noticed text above plugin entry (after 10 minutes) that said “Add the ‘mpopup’ class to a menu item in a custom menu”. But menu items have no field for class name. Had to delete and try something else.
