How to Fix Max Mega Menu Column Display Issues on Mobile and Desktop

Content

Columns not displaying correctly in your Max Mega Menu is a common issue, especially when switching between desktop and mobile views. This guide covers the most frequent causes and their solutions, compiled from community support threads.

Common Column Display Problems

  • Multi-column grid layout not collapsing to a single column on mobile.
  • Submenu items appearing in a single column instead of multiple columns on desktop.
  • Third-level submenus not splitting into multiple columns.
  • Mobile menu settings for columns not taking effect.

Why This Happens

These issues typically occur due to theme or plugin conflicts, incorrect width settings, or the need for additional custom CSS to override default styles for specific screen sizes. The 'Mega Menu Columns' mobile setting often only affects the top-level mega menu grid, not nested submenus within it.

Solutions and Fixes

1. Mobile Columns Not Collapsing

Primary Fix: First, ensure the mobile setting is configured. Navigate to Mega Menu > Menu Themes > [Your Theme] > Mobile Menu. Locate the Mega Menu Columns option and set it to '1'.

Advanced Fix (Custom CSS): If the setting alone doesn't work for nested submenus, you will need custom CSS. The exact CSS selector depends on the number of columns in your desktop layout. Add the following code to Mega Menu > Menu Themes > Custom Styling, replacing the '4' in mega-4-columns with your actual column count (e.g., 2, 3, 6).

@include mobile {
    #{$wrap} #{$menu} li.mega-menu-item.mega-menu-megamenu ul.mega-sub-menu li.mega-4-columns > ul.mega-sub-menu > li.mega-menu-item {
        width: 100%;
    }
}

2. Desktop Submenu Stuck in a Single Column

If your mega menu is only showing one wide column instead of multiple columns on desktop, the panel width is likely too narrow.

Fix: Go to Mega Menu > Menu Themes > [Your Theme] > Mega Menus. Find the Panel Width (outer) setting and change it to Body. This makes the submenu fill the entire page width, allowing columns to form correctly.

3. Distributing Items into Multiple Columns

For long lists of submenu or sub-submenu items that you want to split into columns, use the built-in grid layout builder.

Fix: In your WordPress admin menu editor, set the submenu type to Mega Menu - Grid Layout. You can then use the interface to create rows and columns, distributing your menu items, widgets, or other content as needed.

4. General Troubleshooting Steps

  • Clear Caches: Clear any site, browser, or server caches after making changes.
  • Check for Conflicts: Temporarily switch to a default WordPress theme (like Twenty Twenty-Four) and disable other plugins to see if the issue persists.
  • Provide a Link: When seeking help in communities, always provide a link to your site. Many solutions require seeing the live code to diagnose the problem.

By following these steps, you should be able to resolve most column-related layout issues in Max Mega Menu.
