I had an interesting* issue with Gravity Forms today. I needed to check out some settings on a client site, but when I tried to edit the form, or any of the settings pages, such as the Confirmations or Notifications pages, I received a popup notification advising that the form was currently locked. Not only couldn't I edit the form, but I couldn't even view any of the other settings pages either.
Gravity Form Validation on Default Field Values
Sometimes, usually due to lack of screen real estate, designers will design a form where the field's labels are displayed within the input field themselves, rather than sitting above or below them. I'll admit, they can look nice from a design perspective, but I'm not a big fan of displaying forms like this for usability and accessibility reasons. I'm not alone here either, there's lots and lots of experts that agree. With that said though, sometimes you just have to do what the designer wants.
