Multiple choice polls in Slack can transform how your team makes decisions. Need to schedule a meeting across time zones, gather input on feature priorities, or plan an event where people have multiple preferences? Letting participants select more than one option gives you richer, more actionable data than forcing artificial single-choice constraints.

Does Slack do this out of the box?

No. Slack doesn't support multiple choice polls natively. While you can create simple reactions-based polls, these don't offer true multiple selection functionality. Slack recommends using 3rd-party apps for advanced polling features.

In this post, we'll guide you through using OpenCulture, a privacy-centric Slack app, to create multiple choice polls in Slack.

How It Works: Step-by-Step

Step 1: Install the app

Head over to OpenCulture in the Slack App Marketplace and click the "Add to Slack" button. If you don't have admin permissions, ask your Slack admin to install it for your workspace.

Step 2: Start a poll

Type /openculture poll in any channel to start setting up your poll.

Step 3: Configure your poll

The poll creation form lets you:

• Question (up to 500 characters)

• Choices (up to 100 characters each; 2–10 allowed)

• Enable Multiple Choice — the key feature for this use case

Step 4: Preview and post

You'll see a preview of how the poll will appear in the channel. If you like what you see, click Post Poll to confirm and post the poll to the channel.

Participants can vote by clicking the ✅ button against multiple options; creators manage everything from the same thread.

Why Multiple Choice Matters

Single Choice Limitations

Traditional single-choice polls force artificial constraints. When you ask "What time works for your next week?" and someone can attend Monday, Wednesday, or Friday, making them pick just one option gives you incomplete data. You might schedule for Wednesday when actually more people could have made Friday work — you just never knew because the poll format prevented them from telling you.

Richer Data Collection

Multiple choice polls capture the full picture. Instead of one data point per person, you get their complete preference set. This matters for:

Scheduling decisions: See all the times each person is available, not just their top preference

Priority setting: Let people indicate all features they care about, revealing patterns you'd miss with forced rankings

Resource planning: Understand the full scope of needs rather than artificially limited responses

Preference gathering: Capture nuanced opinions where people genuinely have multiple valid choices

Real-World Use Cases

Meeting Scheduling Across Time Zones

Ask "Which time slots work for you this week?" with multiple selections enabled. You'll see overlaps you'd never spot with single-choice polls. Someone might be available Monday 9 AM, Tuesday 2 PM, Wednesday 9 AM, and Friday 3 PM — forcing them to pick one would hide 75% of their availability.

Set results to hidden until the deadline so people don't game their selections based on current leader. Auto-close 24 hours before you need to send the meeting invite.

Feature Prioritization

Product teams can ask "Which features matter most to your workflow?" and let people select their top 3–5 priorities. This reveals:

• Features with broad appeal across the team

• Niche features that matter deeply to specific roles

• Patterns you'd miss if everyone only picked their #1 choice

Enable participant-added options so team members can suggest features you hadn't considered.

Event Planning

Planning a team outing? Ask "Which activities interest you?" with multiple choice enabled. Someone might be excited about both bowling and escape rooms — why make them choose? You'll discover which activities have enough support to be worth organizing.

Add anonymous voting if you want honest preferences without social pressure about "fun" activities.

Training and Development

Ask "Which training topics would benefit your work?" with multiple selections. People often need help in several areas — single choice polling makes them prioritize artificially. Multiple choice reveals:

• Common skill gaps across the team

• Specialized needs for specific roles

• Breadth of training interests that justify investing in multiple programs

Dietary Preferences and Accessibility

For catered events, ask "Which dietary restrictions should we accommodate?" with multiple selections and anonymous voting. People with multiple restrictions (vegetarian + gluten-free, for example) can indicate both. Anonymity removes any awkwardness about revealing personal needs.

Project Resource Allocation

Ask "Which projects need your involvement next quarter?" Engineers, designers, and others can indicate all projects they're interested in or needed for. This reveals:

• Projects with strong team interest

• Projects that might struggle to find contributors

• People's capacity across multiple initiatives

Availability Polls for Recurring Events

Ask "Which days generally work for your for our weekly sync?" with all five weekdays as options and multiple selections enabled. You'll quickly see which days have the broadest availability, making scheduling decisions data-driven rather than guess-based.

Try It Yourself

OpenCulture offers a 14-day free trial. Install it with one click using the "Add to Slack" button and start creating multiple choice polls in any public or private channel.

Conclusion

Multiple choice polls give you richer, more complete data than single-choice constraints ever could. Stop forcing your team to pick just one option when their reality involves multiple valid preferences, availabilities, or needs.

Whether you're scheduling across time zones, gathering feature input, planning events, or understanding training needs — multiple choice polls let you capture the full picture and make better decisions based on complete information.
