assigning dependent fields

Hi there, We found Zoho recruitment system is effectiveness and close to our needs. but actually have design for desired applicant form that we want to adopt as it shown in this site: http://fd10.formdesk.com/unihouse/form1, herein, we would like to know - before upgrading our account - if Zoho support an assigning dependent fields (like the first question in our design, select an option from drop-down list and other questions appeared), and are there a developers team in Zoho to provide support for customers to design some desired applicant forms?
