I am trying to add an explanation section if a person clicks yes on a form survey. Is this possible>

Hi @Woodall Michelle,
Thank you for posting your question to Microsoft Q&A Forum.
As of now, there hasn't been a direct “show explanation box when Yes is clicked” feature yet but you can use branching logic in Microsoft Forms as a workaround.

To add an explanation section when “Yes” is selected:

• First you have to create your initial question.

Example: “Do you agree with the policy?” with options Yes and No.

• Add a follow-up question for explanation

Example: “Please explain why you selected Yes.”

Set this question type to Text (long answer).

• Then you can enable branching

In Microsoft Forms, click More form settings (⋯) → Branching.

For the first question:

If Yes, branch to the explanation question.

If No, branch to the next relevant question or End of form.

Save and test

When a respondent clicks Yes, they’ll be taken to the explanation question. If they click No, they skip it.

Note:

• Branching works on choice questions only, so your first question must be multiple choice.
• You can add multiple branches for different answers if needed.
• This feature is available in Microsoft Forms for personal, business, and education accounts.
• You can't do this workaround from the Poll feature in Outlook; this has to be done from Microsoft Forms.
