How to 'Nest' categories? [closed]

+8 votes
I am starting some new categories.  How do I "nest" them?

[[Category: Immigration - Ports of Entry|Ports]] should be nested under [[Category: Immigration]] and listed alphabetically under Port.

[[Category: Immigration - Ports of Entry - America|America]] should be nested under [[Category: Immigration - Ports of Entry]] and listed alphabetically under America.

[[Category: Immigrant Arrival Ports - America - New York|New York]] should be nested under [[Category: Immigration - Ports of Entry - America]] and listed alphabetically under New York.

I think if you're on the New York page and you write

[[Category:America|Big Apple]]

You want the current page to be listed under America, not by its real name New York, but by its alias Big Apple.

So the thing after the pipe is an alias for the current page, not an alias for the category.

So, go to an Ellis Island immigrant and write

[[Category:Immigration Arrival Ports - America - New York]]

No alias, because the immigrant keeps his own name.

Click on the red link and write

[[Category:Immigration - Ports of Entry - America|New York]]

and so on.  Assuming the names are OK - no idea what the rules are.

PS I now see that one's already done, but using the long names without the short aliases

PPS That's not right is it,  The alias doesn't change the name that appears, it only changes how it sorts.  Bummer.
Right, RJ, the part after the pipe only affects the sort order.
