thanks for the responses from eelco and mchack. i appreciate it. i guess
part of the problem is i dont understand enough html either :\. it seems
that you have implied you can put anything in a span tag (e.g. a form and a
label). i will look at the template more carefully. i bought the pro wicket
book and went through half of that, so hopefully when i'm done i will have
more advanced questions.
thanks again,
verbal

Basically the two different strategies you have is to either set the
visibility of components (or override isVisible) appropriately, or
build up the hierarchy dynamically. As an example of the latter, you
could have a are in your page you call top bar. When you construct the
page, you decide whether to add the top bar with the login panel, or
the top bar without (e.g. to show the panel that displays the logged
in user's name). The templates example in Wicket examples shows
something similar.
