Hi Jeronimo,

Thanks for your post!!

Based on my understanding, you want to use ContextMenu and MainMenu in your
Winform applicaiton, but you do not know how to edit these 2 menu
components in VS.net IDE. If I misunderstand you, please feel free to tell
me. Thanks

If we drag a MainMenu component onto the VS.net designer, it will appear on
the component tray just below the designer Form. When we select the
MainMenu component in the component tray, the text "Type Here" is displayed
in the Form Designer just below the caption bar, click the displayed text,
and type the name of the desired menu item to add it.
To add another menu item, click another "Type Here" area within the Menu
Designer.
1. Click the area to the right of the current menu item to add a submenu.
-or-
2. Click the area below the current menu item to add another entry to the
same menu.

Then, the edited MainMenu component is associated with the current form.

For ContextMenu, the edit way is almost the same with MainMenu component.
But to associate the context menu with the form or a control on the form,
we should set that control's ContextMenu property in the Properties window.
Once the setting is done, we can run the winform application, and when we
right click that control, our context menu will display out.

For more information, you may refer to the below official document:
