To add menus in WordPress, follow these steps:
1. Log in to your WordPress dashboard.
2. Click on “Appearance” and then “Menus”.
3. On the “Menus” page, you will see a list of existing menus. If you don’t have any menus, click on “create a new menu”.
4. Enter a name for the menu and click “create menu”.
5. Add pages, posts, categories or custom links to your menu by selecting them from the left-hand side of the page and clicking “Add to Menu”.
6. To organize your menu, drag-and-drop items to reorder them. You can also create sub-menus by dragging an item to the right underneath another item.
7. Once you have finished creating your menu, select a “Menu Location” from the checkboxes at the bottom of the page.
8. Click “Save Menu” to save your changes.
Your new menu will now appear on your website.
