WP Better Sub Menus improves the
Appearance → Menus screen when you manage large nested menus.
- Click the colored bar on a parent item to collapse or expand its branch
- Sticky, scrollable left column (Pages, Posts, categories, etc.) while you edit
- Depth colors so nested levels are easier to scan
- Visual changes only — front-end navigation is unchanged
Especially useful when a menu has dozens of items and several levels deep.
- Install from Plugins → Add New (search “WP Better Sub Menus”), or upload a zip whose top-level folder is
wp-better-sub-menus.
- Activate the plugin.
- Go to Appearance → Menus. Parent items with children show a colored expand control on the left.
If your menu has no sub-items, the screen looks the same as before.
