Could we get support for the placeholder attribute? –124.180.123.236 19:21, 22 May 2012 (UTC)

It should already support placeholder attribute since this commit: https://gerrit.wikimedia.org/r/gitweb?p=mediawiki/extensions/InputBox.git;a=commitdiff;h=6b49e7d6d899dfe276c6993d53874475e7bedb5e

If you're using an up to date version, you just need to use placeholder=. :)
