Overview

Form Logic lets you create dynamic forms that adapt based on respondent input. With Logic, you can show only relevant questions for each respondent. No need for them to skip unnecessary questions.

Show a question based on an answer

  1. Click the question you want to show or hide.
  2. In the right-hand panel, open Logic.
  3. Under Hide conditionally, choose Show when or Hide when, then click Set conditional logic.
  4. Click Add condition and pick the question it depends on.
  5. Choose the rule. In this example, Quantity only shows once Product has an answer.
  6. Click Done, then click Publish so respondents see the change on your live form.
To send respondents to different pages instead, see Page logic.

Where logic can be applied

Use page logic in surveys In a survey, certain questions may only be relevant based on the respondent’s previous answers. By editing the page logic, respondents skip unnecessary questions, presenting a more focused and tailored survey experience. Set conditional fields in application forms Application forms often have fields that are only applicable to specific scenarios. Logic can be used to show or hide these fields based on the respondent’s input. Give dynamic feedback in quizzes In a quiz, you can use logic to provide dynamic feedback based on the respondent’s answers. For example, if a respondent selects a wrong answer, you can display specific feedback or redirect them to a relevant section for further learning. Automated calculations in order forms Order forms often involve calculations like pricing, discounts, and taxes. By incorporating logic, you can automate these calculations based on the respondent’s inputs, ensuring accurate and efficient order processing.
