How do I add fields with conditions on my form?

Na Tabela de Pedidos eu quero acrescentar um campo indicando a onde a pessoa deseja receber o pedido, se em casa, na mesa ou avisar quando estiver pronto. 

e eu gostaria de saber se neste formulário existe um campo para que eu possa acrescentar  onde somente aparecer o endereço quando o cliente escolher a opção a domicilio e aparecer a opção numero da mesa quando o cliente optar pela opção de entregar na mesa.

You can add Address field to the form and add some conditions to display the address or table number based on the selection from the drop down.

I have cloned your JotForm to my account and added an address field as shown below:

Now, added the following conditions using Show/Hide field in the form to display the address or table number based on the selection of dropdown.

This is how the conditions work on the form.

Please see the cloned version of your JotForm with the above changes below:
