I'ts possible to create a view (insteat of the ListView / DetailView) whit two tabs.
One tab for the ListView an one for the DetailView similar as the MasterDetailMode ListViewAndDetailView Property, only with tabs.
We have closed this ticket because another page addresses its subject:
ListView - Allow placing the master ListView on right or bottom sides when MasterDetailMode = ListViewAndDetailView
Hello Lukas,
The functionality you want is not supported by default, but it is possible to accomplish your task in the current version of the suite. I have updated the description of a similar suggestion in the Support Center: ListView - Allow placing the master ListView on right or bottom sides when MasterDetailMode = ListViewAndDetailView.
Please try this solution, and let us know how this works for you.
Thanks,
Dennis
