In the FSE themes, there is no work interface for the menus, as in the classic themes, where the menu settings can be found in the WordPress Dashboard ><\/em><\/strong> Appearance > Menus<\/em><\/strong> tab. It complicates the usage of the JetMenu <\/em>functionality, in particular, of the Mega Menu <\/strong>for block themes in WordPress.<\/p>\n\n\n\n

Classic themes are built around the customizer, widgets, and PHP template files. So when working with the classic themes, you use editors like Elementor or Gutenberg for setting up the content, not full layouts. The site structure elements, such as header, footer, and archives, are controlled in code by PHP templates.<\/p>\n\n\n\n

The FSE (Full Site Editing) themes are built entirely for the Gutenberg block editor \u2014 no customizer is needed. You can edit all headers, footers, templates, and global styles visually.<\/p>\n\n\n\n

The FSE themes use blocks for full layouts, including navigation and site structure. Thus, the entire site becomes editable like a page with no coding required.<\/p>\n\n\n\n

Now, the JetMenu <\/em>page provides a clear, classic interface for menu control, which makes the usage of the Mega Menu<\/strong> accessible for the FSE themes\u2019 users. In this tutorial, we use the Twenty Twenty-Five FSE theme to build a header with the functioning Mega Menu<\/strong>.\u00a0<\/p>\n\n\n\n

Create a Menu<\/h2>\n\n\n\n
\n

The process of building a menu is very similar to the classic one. Proceed to WordPress Dashboard > Appearance > JetMenus<\/em><\/strong> tab. Here, you can select one of the existing menus for editing or create a new one. Refer to our How to Create a Mega Menu in Elementor<\/strong><\/a> guide to learn how to create a Mega Menu<\/strong> in the menus\u2019 dashboard.\u00a0<\/p>\n\n\n\n

Once you have added the desired number of menu items, you can set the Mega Menu<\/strong>. For that, click the \u201cItem settings<\/strong>\u201d button.\u00a0<\/p>\n\n\n\n

\"item<\/a><\/div>\n\n\n\n

In the newly opened pop-up, enable the Use Mega content <\/strong>toggle. Then, you will be able to choose the MEGA CONTENT TYPE<\/strong> (\u201cElementor\u201d in this case) and click the \u201cOpen editor<\/strong>\u201d button to set the mega content.\u00a0<\/p>\n\n\n\n

\"enable<\/a><\/div>\n\n\n\n

In the newly opened window, you can set what content will be shown in the Mega Menu<\/strong>. In this case, we add the Listing Grid<\/strong><\/a> widget.<\/p>\n\n\n\n

\"mega<\/a><\/div>\n\n\n\n

Click the \u201cPublish<\/strong>\u201d button once you are ready and return to the menu settings page. In the Item settings<\/strong> pop-up, you can also set up the following aspects:\u00a0<\/p>\n\n\n\n

\"mega<\/a><\/div>\n\n\n\n
