    I have a contextual menu with submenu and some of them are bound to an items source. I use DropDownHeight to limit the height of a sub menu but since the quantity of item displayed can change, it happens that I have space left at the end of my menu when there isn't a lot of item. Is there a way to set a maximum height to the drop down, that doesn't impose a minimum ?

    Thank you,

    Hi Etienne,

    Thank you for contacting us.

    I'm afraid the MenuItem doesn't provide such a property. You would need to manually set the desired MaxHeight in the MenuItemTemplate of the first Grid inside of the Popup named PART_Popup:

    <Popup x:Name="PART_Popup" ...>
             <Grid Width="{TemplateBinding DropDownWidth}" Height="{TemplateBinding DropDownHeight}" MaxHeight="200">

    However I logged this as Feature Request in our Feedback portal, so you can track and vote for the item on the following link:

    Hope this helps.
