Is it possible to have multiple selection for foreign key?

For example:
I have categories and when I write a new post, I can select more then one category.

I know it is possible to code this by my self, but I would like to know if this is also possible with cook, because primary there is only drop select for foreign key.

Not possible right now

There will be a big party when it will arrive.
Everybody wants this, but I must go on slowly for the moment. The basics are not yet stable.

Stay in touch.

for the party, it is a joke , but why not (French Joomla day 2013 ?)

N:m and N:1 are shipped with new version 2.8 !!
