// Static/select: User allocates variable, passes it to function and it's set automatically from input among the strings given to function,
// then you can handle ChangeFunc and ReturnPrevPageFunc if needed.
//
// Dynamic: Function doesn't accept value pointer, user should do operations with handling ButtonPressFunc.
// Right-side text can be set via DrawFunc, which is called on every draw. ReturnPrevPageFunc is also here if needed.
