Do you want to learn how to build better forms to enhance user experience with Drupal? Forms are the key web components for interaction between users and the website. A deep knowledge in the forms workflow will help you to provide an improved user experience while keeping the website access secure and troubleshoot issues with forms.

In this session we will give a general overview of the features that the Drupal Form API provides, from the basiscs to more advanced topics like handing ajax events with forms. In addition, we will review some of the best practices when building custom forms or altering forms with Drupal.
