How to edit form?

Como editar e/ou adicionar perguntas a um formulário? 

Hi irandimfilhom.

Thanks for reaching out to Jotform Support. Unfortunately, our Portuguese Support agents are busy helping other Jotform users at the moment. I'll try to help you in English using Google Translate, but you can reply in whichever language you feel comfortable using. Or, if you'd rather have support in Portuguese, let us know and we can have them do that. But, keep in mind that you'd have to wait until they're available again.

As for your question, you can directly edit or add questions in your Form Builder. You can also go to your My Forms page. Here's how:

1. Go to the My Forms Page.
2. Check the form you want to edit.
3. Click the Edit Form button on the right side of the page.

If that’s not exactly what you’re looking for, can you explain a bit more so I can help you better? 

Give it a try and let us know how it goes.
