The solution is to nest the ListViews:
Markup:

wicket:container wicket:id=optGroups
optgroup wicket:id=optGroup
wicket:container wicket:id=options
option wicket:id=option/option

Hi Jehan,
You'll need to provide your TextField with a model where it can
load/store it's value.
This is easy to do:
new TextFieldString(atext, Model.of());
Kind regards,

I think the problem is there is no model backing your text field.

Passing values other pages using PageParameter is like Query String.
What are other ways in wicket of passing values from one page to other.

Jehan,
It depends on the URL you want to show to the user. If you want a
bookmarkable url, you'll need to use page parameters. If the url doesn't
matter to you, you can simply pass in parameters to the constructor of
the other page, and then call setResponsePage( page instance variable ).
Either use inmethod-grid component or at least see its implementation for
CheckBoxColumn.

Please See following thread:
Yes, when just using a list of options a dropdownchoice ist the best way!
But in my case I need a dynamic select with optgoups and dynamic options.
My problem is solved now. I found a css error in my code.
The solution works fine now also with firfox!

There's no isDisabled in Component, did you mean isEnabled?
How would I have control over individual elements there in that override?
Frankly, slightly longer answers would be very much appreciated. Thanks

I Daniel, how alwaysUpdateModel differs from updateModel? If you have an
required form component that support some clean up logic, it can be coded
inside AjaxFormComponentUpdatingBehavior#onError, and if you need an AJAX
behavior that don't validate the form component, you can
use
debug it and see why its not matched.
