Using Foundation 6 Formatting

Whats the best way of using Foundation 6 CSS with your forms.

I don't want lose the ability to hide fields and use the conditional logic.

The markup is quite different and I'd like the form to look like the rest of my website.

I downloaded the source code and there are so many different scripts and css files I don't know which ones I can let go without affecting the form.

Unfortunately it is not possible to install Foundation 6 in jotform. You can only use CSS3 for designing your forms to your preference. We do have conditions and hide fields available in the jotform builder. Here are several guides that can help:
