I will give you a general answer related to all build-in (out of the box) elements & apps, they are just semi-editable. Always when you use predefined stuff, you will only be able to edit the options, which are offered by the used element/app.
Always when you need specific / expanded functions, you will need to build it by your own from scratch.
If you ask me → i generate almost everything by my own from scratch, this way i make sure, that my own creation will work EXACTLY like i want, without following predefinitions.
So, if the Menu-Bar do not offer you the possibilities you need and also do not offer you any API to interact with it by code → forget about this out of the box-concept → generate your own MENU, giving it your own wished functionalities and functions.
The disatvantage of going this way…
- you need to be able to code
- you will loose a lot of time generating your own functions, systems, elements, APPs and so on.
In most cases this description fits when using predefined stuff.
