For a project I’m working on right now it need to add three links in the footer, something like “Terms & conditions”, “Confidentiality” etc. These links are of course pages defined by the administrator.
I noticed that even if I create a new menu, I don’t have the option to add it to the footer.
Excellent question there. The actual footer doesn’t have a spot for a navigation menu present. But the inputs for custom footer text in the customizer can accept HTML. You could create links in the inputs for the left footer or right footer if you’d like with some code like this:
<a href="http://yourlink.com">Link Text</a> <a href="http://otherlink.com">More Link Text</a>
Just replacing the URL’s with the ones you’d like to use and the text with what you’d like each link to say.
You could also add a custom navigation widget to the footer widget area. That would be another way to add a menu with links in it to the footer. But if you only need just the links and not other content in the footer to balance out the menu visually, I would stick with the HTML in the footer text spots.
