Hi Maxim,
Sure, you can propose anything you want! ;)
The plugin you are referring to seems to be straightforward to implement (a behavior is enough), thus there is no event to handle...
I will take care of it over the WE...
FYI, there is an HowTo about creating simple wicket-jquery-ui behaviors (in case you have other - and specific - needs)
http://code.google.com/p/wicket-jquery-ui/wiki/HowToCreatePlugin1There is also a Part II (the component/widget) but I need to rewrite it due to the last refactoring, and I still have to write the part III (handling events) since a long time!.. :s
Best regards,
Sebastien.
