You can make your forms smarter by showing or hiding questions, sections, or subsections based on previous answers. This keeps forms shorter, more relevant, and easier to complete. You can also prefill answers automatically to save time and avoid duplication.
Show or hide content based on answers
Conditional display allows you to decide when a section, sub-section, or question should appear.
Examples:
Show a Pregnancy section only if the subject’s gender = Female.
Show detailed smoking history questions only if the subject answers “Yes” to “Do you smoke?”.
Show Visit 2 only if Visit 1 was done

How to show/hide a section/sub-section/question based on another question
In the form builder, create a reference question (radio button or dropdown).
Go to the section, sub-section, or question you want to control.
Add a condition linked to the reference question.
Define the logic (e.g. Show this section if answer = Female).
Save.
Prefill answers automatically
You can prefill answers based on earlier responses. This feature works only with radio button questions.
Example: If a subject’s birthdate shows they are under 18, automatically prefill “Minor” in the eligibility step.
