Creating an approval workflow for a customized request form

Hello,

I have created a customized request form in FIM that users are to fill up and submit for rights request. A workflow is required for for request process from the requester an escalation of approvers for the request to be approved or denied.

My challenges are:

1. Adding a control to my xml configuration file that will allow users to select multiple items, a checkbox feature with a list of rights to apply for
2. Creating a workflow for the customized request form, so that the approvers receive mail with the details filled on the form as the body text of the mail.?

How can I achieve these? I will greatly appreciate your help.

Regards,

Josephine
