Best menu for this situation

I’m not sure where the best place to post this is so if a mod wants to move it please feel free!

I am trying to figure out the best menu system for this particular situation:
I will have a map of a very large region. On this map will be dots or whatever for particular locations. There will be something like 115 of them so I will have to implement some kind of zoom/pan tool. Anyway, I would like each dot location to have its own menu - sort of. I’m sure that many of the dot locations will have similar links but not all - some will have more than others, etc.

So I’d love to get some opinions on the best way to handle this. One menu? Many menus? What’s possible? I’m thinking xml is a nice way to go because the files are small and fairly easy to manage but I’m open to suggestions. Also, with many menus - how would you call them to appear/disappear on rollover/rollout of the dot button?

Thanks all for any input! :beam:
