1. Create a new project containing RadMenu in MDI form
2. Add some child windows
3. Run the project
4. Open the menu

FIX. RadMenuItem does not repaint itself after being re-enabled

RadMenu does not clear its IsMouseDown state after being clicked and the pointer leaves the menu item before the mouse button is released

This feature request concerns adding a Right to left support (RTL) in RadMenu.

When RadMenu is on focus and some of the RadMenuItems has visibility set to Hidden those items should be visible in design time.

Menu items should stretch to fill the available area.

After adding a few items in RadMenu, and changing their visibility settings:
1.When turned back to visible, they does not appear
2. When they are collapsed, their empty spots are still there (although AutoSize = true)

int i = 1;
        void radMenuItem1_DropDownOpening(object sender, CancelEventArgs e)
        {
            if (i == 0)
            {
                radMenuButtonItem2.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
                radMenuButtonItem3.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
                i++;
                
            }
            else
            {
                radMenuButtonItem2.Visibility = Telerik.WinControls.ElementVisibility.Visible;
                radMenuButtonItem3.Visibility = Telerik.WinControls.ElementVisibility.Visible;
                i--;
            }
            radMenuItem1.DropDown.PopupElement.InvalidateMeasure();
            radMenuItem1.DropDown.PopupElement.InvalidateArrange();
            radMenuItem1.DropDown.PopupElement.UpdateLayout();
        }

- We have project called ProjectOne with a Form1 in in.
- this form inherits from RadForm
- add RadMenu with one item in it
- Create second project called ProjectTwo with Form2 in it
- make Form2 inherit from Form1.
- design time error appears.

SubMenu items MUST completely occlude the right pane of the Application Menu, regardless of the number of items available in the menu options.

Automatically display scrollbars when total menu item height exceeds the available screen area.

RadMenu accepts keyboard commands even though its parent Form is not active. The normal behavior is that RadMenu processes keyboard only when its parent form is activated.
