You can include the 'Visual analog scale' question type in the questionnaire, which can be found among the layout formats for the 'Categories - Single answer' question type.
The visual analog scale (VAS) allows you to display the answers on a scale in the form of visual responses (emoticons).
You can set up a VAS question by inserting a 'Categories - Single answer' question type in the questionnaire. In the question settings on the right-hand side, in the 'Basic' tab, under the 'Layout' setting, select the 'Visual analog scale' option.
You will then see the 'Number of answers' setting in the 'Answers' segment of the settings, where you can choose between 2 and 7 answers.
