We have a wordpress site and we want users to be able to answer to some surveys.
Which is the best option for including this surveys if we want these features ?
- User don't have to be logged in to complete a survey
- Some questions can appear depending of some other question's answer
- Some questions can appear depending of if the user is logged in or not
- Questions should be splitted on few pages, and a progress between pages should appear.
Is there any plugin that can be used with these features ?
