dynamic double dropdown in a page with two forms

Hi. I'm facing a problem with a double dropdown.

​

If I preview the form alone all works fine.

​

When i use the same form inside a page with another chronoform form the second dropdown desappears selecting each first dropdown value.

​

May be there's some bug?

Ok, i find the problem. in the primary form there is a jquery datatable. Probably the double dropdown has some compatibility problem with it.

​

Any workaround?
