Answer 1

While I was finding answers, I got the following:

This my code in xhtml:

I use properties "redered", rendered="#{activacionOpcionesMB.activarItemPermisos()}", where activacionOpcionesMB.activarItemPermisos() is my MB.

This is my MB:

package co.com.patios.mb.util;

 import javax.faces.bean.ManagedBean;
 import javax.faces.bean.RequestScoped;


 @ManagedBean (name = "activacionOpcionesMB")
 @RequestScoped
 public class ActivacionOpcionesMB {

    public boolean registrarPatio = true;

    public void activarItemPermisos(){
       if(true){
          registrarPatio = false;
       }
    }


 }

"registrarPatio" is the data that I use for active o unactive menuItem, for default it's true.

The method activarItemPermisos() is where I active the menuItem, here I use conditional and after I assing to registrarPatio false.

You can use "if" for validate access to the different option in their applications.
