WordPress shows admin menu items on the base of capabilities granted to a role or directly to a user. You should work with capabilities 1st to show/hide admin menu.
Often we meet a situation when we need to hide from user some part of admin menu, but they use the same capability, like ‘manage_options’. For example, you have 2 plugins which create menus A and B protected by the same capability manage_options. You wish to show for a role menu A, but not show menu B. You can not revoke ‘manage_options’ from a role, as it will lose access to menu A too. In this case and only in this case you may use admin menu blocking feature from URE Pro. URE Pro works on the base of WordPress permissions system and does not try to replace it.
