The ExpandAnimation and CollapseAnimation properties
of RadMenu are used to customize the way groups 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 ExpandDelay and CollapseDelay properties
set the period of time (in milliseconds) between the mouse entering / leaving a
menu item (or clicking the item - if ClickToOpen = "True") and
the children starting to expand or collapse respectively.
