Surveys allow you to combine multiple polls into a single.
A Survey is a collection of individual polls grouped into one structured experience. Instead of launching multiple separate polls, you can ask a series of related questions in one go, making it easier to engage your audience and collect meaningful data.
Go to Audience Interactions → Polls & Surveys
Select Survey as the type.
A Survey will appear below, allowing you to edit the survey itself and the polls within it.
You can add exactly the same poll types as you would in regular polls.
More information about regular polls can be found here.
There are 4 different poll types
In all poll types, you can add open text field by clicking "Add extra field". You can also allow multiple answers, as well as show the poll results immediately to the attendees.
