CATWALKER – Edit plugin to block second select and submit on select

Olá .
Recentemente instalei o plugin do CATWALKER Que permite Intersec??es Entre CATEGORIAS . ELE Lista dois selects. Estou precisando que o segundo select só fique ativo após selecionar uma op??o do primeiro, e quando ativar submeta automaticamente após selecionar a op??o. Espero ter conseguido explicar corretamente. Espero que entendam.
