The Placeholder perk allows you to add HTML5 placeholders to your Gravity Form fields. What are placeholders? They’re short hints that display inline in form input fields (and textareas) that help users fill out the fields with the correct data.
This perk adds a new field setting for fields that support the placeholder property. More on that below. After you’ve specified the placeholder for a field, the Placeholder perk handles updating the field’s input HTML to include the placeholder attribute. For browsers that support placeholders (like Firefix, Chrome and Safari), this functionality will work natively. That means no special scripts!
