Standard and custom properties allow for:

• Input masks (using jquery.inputmask)
• Select2 replacement of select boxes
• Private elements, visible only to administrators
• Unique values per element

Viewing Source

At the heart of a YAML Form module’s form elements is a Drupal render array, which can be edited and managed by developers. The Drupal render array gives developers complete control over a form’s elements, layout, and look-and-feel by allowing developers to make bulk updates to a form’s label, descriptions, and behaviors.

States/Conditional Logic

Drupal’s State API can be used by developers to provide conditional logic to hide and show form elements.

Drupal’s State API supports:

• Show/Hide
• Open/Close
• Enable/Disable

Multistep Forms

Forms can be broken up into multiple pages using a progress bar. Authenticated users can save drafts and/or have their changes automatically saved as they progress through a long form.

Multistep form features include:

• Customizable progress bar
• Customizable previous and next button labels
• Saving drafts between steps

Email/Handlers

Upon form submission, customizable email notifications and confirmations can be sent to users and administrators.

An extendable plugin that allows developers to push submitted data to external or internal systems and/or applications is provided.

Email support features include:

• Previewing and resending emails
• Sending HTML emails
• File attachments (requires the Mail System and Swift Mailer module.)
