I was building with a menu panel yesterday. I found the following issues...

1. MenuItems & DateMenuItems have left padding to push them right of a vertical spacer so icons can be aligned to the left whereas TextMenuItems and ComboMenuItems are aligned all the way left. Only MenuItems have an Icon parameter, so DateMenuItems either need an Icon or need to be aligned with TextMenuItems. Alternatively, I'd recommend left aligning these controls and allowing all of them to have Icon parameters, and only when they do, aligning them with space for the icon.

2. CanActivate="false" works properly on submenus, but not first level menupanels. That is, I am able to click-select this control in this control path:
<ext:MenuPanel><Menu><Items><ext:TextMenuItem CanActivate="false">...
... but not this control in this control path (this is the proper behavior): <ext:MenuPanel><Menu><Items><ext:MenuItem><ext:Men u><Items><ext:TextMenuItem CanActivate="false">...

3. Tooltips do not show in MenuItems.

4. Notes not supported in all MenuItem controls. Some yes, some no.


5. There should be some way to set the Calendar to a read-only setting, i.e. show a date that is selected on the page in another fashion.
