# Custom Field

## What is the Custom-Field?

The Custom-Field is an input-field which can be enabled in the start-quiz modal. The custom-field has to be named, and
then it will be displayed if a player wants to join.

## Use Case

Imagine you're a teacher, and you want to know the real names of your students, but you don't want everyone to see
who is behind which username. That's where the custom-field comes into play. Players can enter their username and their
real name and only the admin (you) can see which username belongs to which real name and which real names exist. The
data can be obtained by downloading the quiz-results at the end. In the spreadsheet, you can then see all the data.

## Notes

- There is no validation at all. Users can also leave it empty, enter numbers and more.
- The value gets saved for future use, so make sure to clear it before starting a new quiz.
