Simple step-by-step guide how to create a menu
Step 1 – Open Appearance ➜ Menus ➜ “Give a name!” ➜ Create Menu in WordPress
Step 2 – Checkmark pages to menu from the column on the left and click on Add to Menu button. Also checkmark the Primary Menu for location
Step 3 – Drag and drop items and set pages into the order you prefer
Step 4 – You can also create sub-menu (multilevel menu) in this phase. Actually not recommended because it’s not mobile-friendly and people usually don’t want to use this kind of navigation
Step 4 – Edit item labels if it’s needed. Menu labels must be short and clean.
