jquery widget combobox dont works in nintex forms

Question asked by jose.fidalgo on May 23, 2017

I need to implement a combo box where the user use autocomplete.
I have the same development in C # .NET and it works correctly. But in nintex gives a warning that does not support the combobox property.

}, 2500 );
this.input.autocomplete( "instance" ).term = "";
},

_destroy: function() {
this.wrapper.remove();
this.element.show();
}
});

cmoeda.combobox();  -------------> gives error why?
