Smart Form

Smart Forms are dynamic forms in which the next questions are based on the previous answers responded by the users of the forms

Features

This project makes it easy for developers to build dynamic forms with these features:

• Get the next question based on the current question and the user's previous responses
• Get the question text which can be dynamically changed based on the user's previous responses
• Count the number of steps to the end question. This number can be used to build a progress bar.
