I have Gravity Forms and Salient Installed. If I have "Fancy Drop Downs" in the salient theme enabled, most everything works. However, if I use a List Field in Gravity Forms and then turn one of the columns into a DropDown using the following code:

/* Facilities List */
add_filter( 'gform_column_input_1_101_1', 'bs_facilities', 10, 5 );
function bs_facilities( $input_info, $field, $column, $value, $form_id ) { return array( 'type' => 'select', 'choices' => 'Terminal,Drop Yard,Warehouse,Other' );
}

Then the first row's dropdown will work, but if I add additional rows, the drop downs will not open. 

There is also an error that arises in the console that I'm not sure if it's directly related to the issue or not.

I have disabled Fancy Drop Downs in the Salient theme for now to get it to work. But wanted to report this as a bug.
