A context menu is a menu on a user interface (typically a GUI), such as the right-click function in computing. The context menu offers a range of options, such as creating folders, for example.

When you right-click, you will get a sub-menu appropriate for the context on which you clicked.
Menu (In the context of Computers)
Context sensitive commands are displayed by shortcut menus. The shortcut menu, also referred to as the right-click menu, is accessed when a user right-clicks a selection.
It is a menu with items that are relevant to what you are doing at that time. Shortcut menus from a right click on your mouse or the shortcut menu key on your keyboard normally show items that are relevant to what you are working in. In other words they are giving you options based on the context of your work.

Depends on the context of the question. I assume menu categories to be things like "lunch", "dinner", "picnic", "holiday", "brunch", etc.
Right-click typically presents a context-sensitive menu relative to the object that was clicked.
