[pmwiki-users] input select box and multiple default values

[noskule]

hi list
I try to use a select box with per default seleted item. But it seams
that it is only possible to select one entry, see:


http://www.pmwiki.org/wiki/Cookbook/InputSelect

the pmwiki example:
(:input select name=abc 1 alpha size=3 multiple:)
(:input select name=abc 2 beta selected=selected:)
(:input select name=abc 3 gamma :)


I need something like
(:input select name=abc 1 alpha size=3 multiple:)
(:input select name=abc 2 beta selected:)
(:input select name=abc 3 gamma :)
(:input select name=abc 4 delta selected:)


Note: I don't no why on the pmwiki example is written
"selected=selected". "selected" only still works.

is there a way to pre-select "beta" and "delta"?
thanks for any hints
