Hello,

If I understand right you can use a buildSelect to make what you want.

Thanks for your answer, it's not the 'buildSelect' for it's used when the server response can not build the select element.

The “ajaxSelectOptions” and 'complete' event can be used to parse and do other things when the server response is returned.
