Best way to provide navigation similar to wordpress
I would recommend going with a "Structure". This would be the build in way of doing it. You can setup the Structure to have it's own fields to control different "Pages" OR you can have it only use a related entries field and link to other entries anyway you like.

This topic has been discussed quite a lot and you have some great posts here:


Would you use a Structure as navigation over multiple sections (channel entries, indexes and singles)?
Multi-lingual site navigation made of singles, channels and structure
How do you handle complex navigation in Craft?


There's also "Plugin" solutions out there like https://github.com/am-impact/amnav.
