Interested in any method or insight into the best way to determine what menu items are contained in a context menu compared to the main menu. Should both menus contain all the same entries depending on the object being used?
Or should the right context menu be more concise compared to what is available in the main menu?
Any exercise to determine menu grouping?
The best way to determine menu items is to conduct research (a card-sorting exercise) with your target audience. That would give you insight into the user's mental model.
Generally, menu items that are directly enable the user to complete a task & avail value out of your system should be included in the main menu. Items that compliment these menu items & indirectly assist the user are housed in the right context menu.
Should both menus contain all the same entries depending on the object being used?
No. For example, just open the context menu anywhere on this page. It most likely is not going to be a duplicate of any other menu.
Any exercise to determine menu grouping?
It seems the best way to determine the grouping is to take a look at the examples and repeat the same pattern so the expected context menu items are not left out. As for the other menu items that might be specific to your application, you may want to include only the ones that make sense to use in the context.
