Just create your own FeedbackPanel subclass and add:

    public boolean isVisible () {
        return anyMessage();

Hello, I am playing with FeedbackPanel. I put it in a page like this:

<div wicket:id="feedbackHolder" />

I notice that when having no messages, it always take up some space.

How can I make FeedbackPanel occupy zero space when having no messages?

Wicket way? or CSS?

Any help is really appreciated.
