Webform commonly used to build a complex contact form or multiple feedback forms. This module allows you to create and manage as many forms as you need. Using the Webform module, we can completely customize what data we collect with our contact form. This functionality is available for both Drupal 6 and 7 although there might be slight differences in the interface.

Consider we need Developer for different job position in our organisation. For this we are creating a Contact form to allow Developer for contact us. We are taking Different field including 'Name', 'Email id', 'Qualification' and 'Work Experience'; where 'Work Experience' field having two options 'Fresher' and 'Experience'.
