Uhd disk and joining the menu files to the movie file

[Wire1078]

Hi could anyone point me in the right direction please.
I'm new to this group and to mkv. How do you join the mkv files together to make a uhd file thst has menus etc?

Thanks Peter

MKV files do not support menus.

If you want the "disk experience", you should use the backup function, which will re-create the Bluray/UHD file structure, complete with menus.
