+Usually, the corporation menu items will be shown in groups (e.g. MDM, Admin):
+The menu bar contains menus with menu items, for each screen, e.g. the menu Admin contains **Statistic** and **Company** screen.
+But sometimes you want flat menus, e.g.
+{{:vaadin:vaadin_corporation_menu_flat.jpg?nolink|}}
+This can be done with your own Menu implementation, e.g.
+<file java>
+public class FlatMenuBarCorporation extends WebMenuCorporation
+{
+    public FlatMenuBarCorporation(IApplication pApplication)
+    {
+        super(pApplication);
+    }
+    @Override
+    protected IMenuItem addMenuItem(String pId,
+                                    String pGroupId,
+                                    String pAction,
+                                    String pActionCommand,
+                                    String pGroup,
+                                    String pGroupImage,
+                                    String pShortcut,
+                                    String pText,
+                                    String pImage,
+                                    boolean pUseSeparator,
+                                    boolean pToggle)
+    {
+        if ("Admin".equals(pGroup))
+        {
+            UIMenuBar bar = getMenuBar();
+            UIMenuItem miItem = createMenuItem(pAction, pActionCommand, pText, UIImage.getImage(pImage));
+            bar.add(miItem);
+            return miItem;
+        }
+        else
+        {
+            return super.addMenuItem(pId, pGroupId, pAction, pActionCommand, pGroup,
+                                     pGroupImage, pShortcut, pText, pImage, pUseSeparator, pToggle);
+        }
+    }
+}
+</file>
+To use the custom menu, simply change the corporation menu class name in your deployment descriptor, e.g.
+<file xml>
+<init-param>
+  <param-name>Application.Menu.corporation.classname</param-name>
+  <param-value>com.sibvisions.apps.vaadin.FlatMenuBarCorporation</param-value>
+</init-param>
+</file>
+In newer versions, it's possible to set:
+<file xml>
+<init-param>
+  <param-name>Application.Menu.corporation.groups.flat</param-name>
+  <!-- comma separated list of group names -->
+  <param-value>Admin</param-value>
+</init-param>
+</file>
+instead of your custom menu implementation.
