OK, that made no sense to me. I understand that english isn't your first language and I'm OK with trying to struggle through.
Lets start with this:
1) Do I need the ARI YUI menu or ARI EXT menu? I installed the ARI EXT already but see that you have the YUI and now I'm confused.
2) Once I select a position (protostar nav pos 1) and publish it, what else do I have to do?
Answer #1 - ARI Ext is the correct download for the default Protostar template.
Answer #2 - Turn off mainmenu module; set ordering on breadcrumbs to follow ari ext menu; enable ari menu.
Question #3: How do you style the ARI ext menus like the prototype menus and/or where do you have default styles documented?
Thanks
