There are two parts to creating a custom menu:
(1) designing the menu, and (2) applying the "Custom Menu" widget.
Some themes do not natively support menus, but you can use the “Custom Menu” widget to add any menus you create here to the theme’s sidebar. You will know if your theme does not support top-menu customization if the menu page displays a written statement: "The current theme does not natively support menus, but you can use the "Custom Menu" widget to add any menus you create to the theme's sidebar."
(i) Designing the Menu
Items in your custom menu can be linked to external webpages, pages in your blog, and categories. You might want to create a custom link menu item if you would like the menu item to link to an external site, such as your personal website or a youtube video.
- To create a new custom menu, go to "Appearance" >> "Menus", and click "Create Menu" next to your existing main menu.
- Type in a custom menu name and click "Create Menu."
- After you have added all your items, following the directions below, you can drag and drop them to place them in the order you want. You can also change the name of each item by clicking on the drop down arrow to the right of each item.
Adding External Links
- To add an external link to your menu, simply copy and paste the URL of the site you want the item to link to in the "Custom links" box.
- Then add a label to your menu item, such as "Personal Website," then click "Add to Menu."
- The menu item will appear as a gray menu item to the right, from which you can drag up or down in the order you would like them to display on your blog.
- To add existing pages to your custom menu, select the pages you would like to add in the "Pages" box and then click "Add to Menu."
- To add categories to your menu, select the categories you would like to display on your menu and click "Add to Menu."
(ii) Applying the "Custom Menu" widget
If your theme does not support custom menu at the top menu bar, you can add multiple custom menus to a sidebar widget on your blog.
- To add your custom menu widget to the sidebar, click on "Widgets" under "Appearance."
- Drag and drop the "Custom Menu" widget to the sidebar on the left and choose which custom menu you would like to display.
- You can then go your blog and see how it looks.
