Can you provide more code to clarify your use case? A quickstart would be
helpful.
Without deeper insight into your project, I would simply implement a
reusable panel like this:
<wicket:panel> <!-- reusablepanel starts here -->
<section class="card" aria-labelledby="sectionheader" wicket:id="
*webmarkupcontainer-providing-necessary-attributes*">
<div class="card-header"><h1 wicket:id="*for-example-this-could-be-a-label*"
id="sectionheader">Lorem ipsum dolor sit amet</h1></div>
<div class="card-content">Content ...</div>
</section>
</wicket:panel> <!-- reusablepanel ends here -->
In java you could then use this as an one-line element along the lines of:
new ReusablePanel("panel-id", "header-id");
