Dear JapanTown,
I’ve duplicated the Fuji demo and enabled the RTL mode (using the plugin I’ve mentioned) here: https://satoristudio.net/test/fujirtl/
The only issue I see right now is that the top menu submenu items shift over the edge of the submenu box; this can be corrected by adding a line of code to the style.css file, as I’ve done in the demo:
.rtl #nav-primary ul ul a { text-align: right !important; }
If you have any questions or comments, I’ll be happy to answer them!
Sincerely,
Andrew | Satori
