WordPress has a built-in widget by default called “Meta”. The functionality of this widget is quite simple. It displays a set of links that change dynamically depending on the user's login status. That is, whether the user is logged in or not. This widget displays the following links — site admin (or registration), login (or logout), post RSS, comment RSS, and .
In one of my projects, I needed to limit the number of links in the menu. I wanted to keep only the first two — registration and login — and remove the other three — RSS + WP — as unnecessary.
