To create your navigation head on over to Appearance > Menus and click on “Create a New Menu”, give your menu a name and click save.
Once you have created your menu it’s time to add some pages/links to it.
On the left you can select from Pages, Posts, Custom Links & Categories to add to your menu. Tick the checkboxes and click “Add To Menu”.
Once you have added your menu items you can drag them around to rearrange them in the correct order you would like.
CityLister offers you one menu location to choose from – “Main Menu” – pretty self explanatory. Choose this and click "Save Menu".
