AppearanceAutomaticthe overall appearance of the menu

FrameMarginsAutomaticmargins to leave inside the menu frame
ImageMargins0margins around the image of the displayed menu
ImageSizeAutomaticthe overall image size of the displayed menu
MenuStyle{}style specifications for menu items

Use Delimiter to separate menu items:
The labels can be any expression:
Use different display appearances for the menu:
Remove extra whitespace around a label with no ascenders or descenders:
By default, ActionMenu is enabled:
By setting Enabled->False, the menu is disabled:
By default, the button function is sent to the kernel for evaluation:
By setting Evaluator, the button function is evaluated in the front end:
Change the field size:
Add margins within the menu:
Add margins outside the menu:
Specify the overall image size:
By default, action menu functions are evaluated on a preemptive link, which times out after five seconds:
Use Method to evaluate button functions on the main link, which never times out:
Choose between various graphics objects:
Control the range of a graphic:
ActionMenu has the same effect as a Button series:
