[EM] question about open party list PR

[James Cooper]

hi everyone,

hopefully this isn't OT.

Iraq's election was just conducted using closed list PR.  as I
understand it, there were over 7000 names across all the party lists.

If they had used open list PR, would voters have to select across all
7000 names?  or do countries that use open list partition the names by
geographic region or some other method?

thanks
