The screenshot element is used such that the respondents can clarify their answer by showing a screenshot. You can help the respondent by giving a label that tells the respondent what to do and which element they selected for the screenshot. You can also provide a ‘Hint text’, that provides extra information on how to take a screenshot, for example. It is also possible to mask elements in a screenshot, the content of the elements will then be hidden in the generated screenshots. This is used for privacy-sensitive content on your website. If your form consists of several pages, you can also choose to show the screenshot element on all pages.
It is worth noting that the screenshot element requires your CSS code to be publicly accessible for it to work fully. If your CSS code is not public then it will not show the screenshot properly in the inbox.
