Kendo Dropdown option label and field names and lazy loading of data

[Haritos Hatzidimitriou]

Hello,

I'm currently trying to use the (lazy) Kendo DropDownList (not sure what the difference is with the non lazy). And there a couple of things I need and I'm not sure how to implement

1. I need to specify the 'select option' text (Kendo calls it the optionLabel ) 

2. I need to have titles for my elements (code, description)

3. Ideally I would like to load my data only before rendering and not having to provide them in the constructor.

So the end result should look like this: 

Any pointers as to how I should implement the above?

The 3rd one seems the most tricky, but 1 & 2 should be doable without much code I imagine. When I can get it to work I will be happy to provide the enhanced dropdown to the community via PR.

Thank you in advance!

Still Using Wicket-Kendo 7.10.0 by the way.

Ok After some further digging it looks like Kendo Dropdown has elements called scriptTemplate, headerTemplate, footerTemplate and noDataTemplate (all of them of type="text/x-kendo-template")

to handle the list of data, the header etc. So I assume I have to use (and extend) the KendoTemplateBehavior class but I'm not really sure how to do it and how to tie everything together...

Here is a Dojo of how it all works:
