Hi Kjell,
We currently do not provide support for 'Cross Frame Menu'. Our development team has confirmed this to be a feature request and would plan to implement this in any of our future releases. We would update you once this feature is implemented. The Menu can be databinded using the 'syncfusion:MenuItemBinding' by setting the 'DataMember' property to the desired datamember.
Kindly view the Online Documentation link below for more details:
