How to add the ability to hide drawer elements in the settings?

The drawer elements are written in config.java. How to hide certain elements if the checkbox is checked? In config.java, the code for this content is:

public static void configureMenu(SimpleMenu menu, ConfigParser.CallBack callback){ List<NavItem> secondTabs = new ArrayList<NavItem>(); secondTabs.add(new NavItem("WebView", WebviewFragment.class,new String[]{"http://google.ru"})); menu.add("Google", R.drawable.ic_details, secondTabs); callback.configLoaded(false); } 

In SimpleMenu Activation:

 public class SimpleMenu extends SimpleAbstractMenu { public SimpleMenu(Menu menu, MenuItemCallback callback){ super(); this.menu = menu; this.callback = callback; } public MenuItem add(String title, int drawable, List<NavItem> action) { return add(menu, title, drawable, action); } public MenuItem add(String title, int drawable, List<NavItem> action, boolean requiresPurchase) { return add(menu, title, drawable, action, requiresPurchase); } } 

In SimpleAbstractMenu:

 MenuItem item = menu.add(R.id.main_group, Menu.NONE, Menu.NONE, title).setCheckable(true).setOnMenuItemClickListener(new MenuItem.OnMenuItemClickListener() { @Override public boolean onMenuItemClick(MenuItem menuItem) { callback.menuItemClicked(action, menuItem, requiresPurchase); return true; } }); 

In activity_main_drawer.xml:

 <?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android"> <group android:checkableBehavior="single" android:id="@+id/main_group"> </group> </menu>
