WordPress navigation refers to the menus that are used to help users navigate a website. Navigation menus are an important part of any website, as they provide a way for visitors to easily find the content they are looking for, and to move between different sections of the site.
WordPress provides a built-in navigation menu system that allows users to create and customize menus for their site. The menu system is located in the WordPress Dashboard under Appearance > Menus. From here, users can create new menus, add menu items, and customize the appearance and functionality of their menus.
Menu items can include links to pages, posts, custom post types, categories, tags, and external URLs. Users can also add sub-menus to create dropdown menus or hierarchical navigation structures. The appearance of menus can be customized using CSS or through the use of plugins and themes.
WordPress also includes a number of built-in functions and hooks that developers can use to add additional functionality to the navigation system. For example, developers can create custom menu walkers to customize the HTML markup generated by WordPress, or they can use filters to modify the menu data before it is output.
Overall, the WordPress navigation system is a flexible and powerful tool that allows users to create and customize menus to meet the specific needs of their website. With the ability to create custom menus, add sub-menus, and integrate with external URLs, the WordPress navigation system provides an effective way to help users navigate a website and find the content they are looking for.
