dhtmlxform connector with dropdown list

can i use form connector with options connector ?
is not working :neutral_face:

ok, i figured it out
select needs at least 1 option:
this one is working:

and this not:

dhtmlxform.js:1208 Uncaught TypeError: Cannot read property β€˜value’ of undefined

It was not expected limitation, problem was confirmed and fixed, in final version of dhtmlxform it will work without necessity to have at least one option in the select.
