When you want to add an item to the menu, it depends what it is for how easy it is to add.
- You can add a page by simply choosing the page
- You can add a post, although it can be hard to find if not recent.
- You can add a category by choosing which one
- You can add a custom link, but where do you find that link?
All you need is the url of the page you want. Therefore the most easy way to find that link is to open a second tab, go to the page you want the link to reference, copy the url from the top of the browser. Not go back to the menu editing and paste in that link. lastly, don’t forget to give the link a useful name to be shown in the menu!
