I have been editing the forms manually after the initial design is created. This is BEFORE any changes are made.
From within Dreamweaver, I click the form preset name, and at the bottom of the page click Edit form. Drill down to the fields I want to remove the validation from and uncheck the validation box. I then save the preset under either the same or a different name. I have tried both. If I go back into edit the form immediately after that, before making any changes are manually made, the validation boxes are checked again.
Like I said this is just while creating the initial form. Its a royal pain to have to keep unchecking the validation box.
If nothing can be done, I can live with it, just extra work.
