Question details

The user is attempting to create a choice question with a drop-down list format but cannot enable the option for respondents to select multiple answers.

Product: Microsoft Forms
Device & OS: not provided
Scenario: Creating a survey or quiz requiring users to choose multiple options from a collapsed drop-down list.
Observed behavior: The 'Multiple answers' toggle becomes greyed out and entirely disabled as soon as the choice question is configured to use the drop-down format.

Before you start

Please note that this is a current by-design limitation within Microsoft Forms, not an account error or software glitch.

Solution 1Recommended

Use a Standard Choice Format Instead of a Drop-down

Since Microsoft Forms restricts multiple selections in drop-down menus, you must revert the question to a standard checkbox format to allow multiple answers.

Microsoft Forms currently only allows single-choice selections when the drop-down style is applied. To collect multiple answers from respondents, the standard choice display (checkboxes) is required.

Select the question

Open your Microsoft Forms survey and click on the specific Choice question that has the Multiple answers setting greyed out.

Disable drop-down formatting

Click the 'More settings for question' (three horizontal dots) icon in the bottom right corner of the question block and uncheck the 'Drop-down' option.

Enable multiple answers

Once the question reverts to the standard list format, toggle the 'Multiple answers' switch at the bottom of the question box to the ON position.

Workaround Successful: Your respondents will now see all available options as checkboxes and can select more than one answer.

Solution 2

Submit a Feature Request to Microsoft

If a multi-select drop-down is critical for your form's design, submitting official feedback can help prioritize this feature in future Microsoft Forms updates.

Frequently Asked Questions

Can I use third-party add-ins to force multiple selections in a Microsoft Forms dropdown?

No, Microsoft Forms does not support external add-ins to modify core question behaviors. The restriction on multi-select dropdowns is hardcoded into the platform.

Why does the multiple answers toggle grey out when I click drop-down?

This is a by-design limitation set by Microsoft. The drop-down element used in Microsoft Forms is currently programmed to only accept a single value selection per user.

What is the best alternative to a dropdown if I have a very long list of choices?

If you need multiple answers for a long list, you must use the standard choice format. To make it more manageable, consider breaking the list into logical categories across two or three separate multi-select questions.
