I recently got asked how to create pages from your categories as a way for separating out different types of posts. You might notice that I do that on my own blog so that people interested in learning about plugins don’t have to sift through all the posts on social media, etc. It’s very easy to do. Just go to Appearance > Menus and then use the Categories box just like you would the Pages box to check the categories you want and click the Add to Menu box.
If you are not seeing the Categories box (or any other box you are looking for), simply use the Screen Options dropdown at the top right hand of the page to check off the things you want to see (and get rid of the things you don’t!)
