People don't like answering a lot of questions - to receive higher response rates, we recommend letting people only answer the questions they want . However, there are questions you want respondents to answer before submitting the serviceform - to make sure you don't receive empty responses, you can make them required. Required questions are marked by an asterisk (*).
Here's how you can set up required questions.
1. Once you select a question type you want, and when you hover over the question, you will see a Required checkbox. Tick the box to make a field or question to be required.
2. Once you have ticked the required checkbox, your respondents will see a Required* text next the to any field or screen that you have set required to.
