Hello everybody,
I'm wondering if there is a way in Wicket to generate unique html IDs and to
then add them in other places in the html, without having to write any boiler
plate code in each panel that I have.
For example in the following panel I need the ID of the h1 tag to be put into
the aria-labelledby attribute in the section tag.
<wicket:panel>
<section class="card" aria-labelledby="sectionheader">
<div class="card-header"><h1 id="sectionheader">Lorem ipsum
dolor sit amet</h1></div>
<div class="card-content">Content ...</div>
</section>
</wicket:panel>
Hardwiring it like in this example of course won't work if I use the same panel
class multiple times within a page due to duplicate html IDs.
While I know I could add WebMarkupContainers for the section and the h1 to my
Java code and manually wire them together with an AttributeModifier in Wicket,
I woud prefer to have some application wide code which recognizes this
constellation in the html file and automatically generates and inserts the IDs.
Maybe somebody can push me in the right direction, how I could accomplish this
with Wicket, if it's possible at all.
Kind regards,
Daniel
