Hi,
I have a version Chronoforms V4.
How can I do to hide and show box, eg:
I have a select box (Country), I choose the United States and shows me on the bottom of the next select box (State) like in the image below.
Additionally, I would like to after selecting the box (Country) Canada appeared to me to be boxed (Provinces Canada).

I would also like to do to automatically format a phone number in the Text box while entering a number in this field as in the picture: (123) 456-7899. The user types the normal number, 1234567899th
Nor do I know how to do field validation:
I have 6 fields required to fill but if you fill only 1 or 2 boxes of 6 no matter which validation is approved and you can send the form and the other fields do not have to be completed and required.

Please help, do not know much about javascript, but I was looking for these solutions not found.
