I'm currently using struts 2.0.14.
The select tag works fine in Firefox as always.
Do you maybe know of another way to correct this problem?
You'd be better off asking on an HTML forum; if the HTML being generated by the Struts tag is correct then there's nothing Struts can do to fix IE. If the HTML being generated is incorrect then you should file a JIRA issue against the bug.
