The ExpandAnimation and CollapseAnimation properties
        of RadToolBar are used to customize the way the dropdown items
        (RadToolBarDropDown and RadToolBarSplitButton)
        are expanded and collapsed. For each expand or collapse animation, you can specify
        Type and Duration:
    
    
        - The Type is chosen from a list of predefined animation effects.
- The Duration is set in milliseconds.
        To disable expand animation effects, set the Type to AnimationType.None.
    
    
        The subproperties of the ExpandAnimation and CollapseAnimation properties can be
        modified both on the client and the server.
