Hiding Components based on style

I am using Wicket 1.3 and was wondering if there is a way to hide components
in the HTML itself.  Here's the issue, say I have two forms and two
different styles.  In one style I want to display all the form fields,
however in the other one I want to display only a couple of them.  I
currently have two HTML files, one for each style, but I can't seem to find
a way to hide the form fields aside from using CSS and adding display:none.
Is that the only way to do it?

Thanks!
