disable browser context menu

[abthere]

Is there a way to disable the browser context menu by default for the entire application and only show the context menus defined for individual widgets? I know it will compromise the accessibility, but the users insist to only see the context menus when defined or nothing at all.

We don't provide a way to do this because it breaks accessibility, breaks browser built-ins like copy/paste/auto fill, breaks browser plugins, breaks OS features, and breaks internationalization in some cases (IMEs).

We'd recommend looking more closely at your users' requests. Probably once they realize what would be lost they will rescind the request.
