Build a FAQ system in Bubble with an expandable accordion interface, a FAQ data type with question, answer, and category fields, a search bar that filters across all entries, and an admin interface for managing FAQ content. This provides users with instant self-service answers and reduces support load.
Overview: Building a FAQ System in Bubble
This tutorial walks you through building a FAQ page with an expandable accordion interface in Bubble. You will create a FAQ data type with categories, build a Repeating Group with expand/collapse behavior using custom states, add search filtering, and create an admin page for managing FAQ entries. This is ideal for any app that needs a self-service help center.
Prerequisites
- A Bubble account with an existing app
- Basic understanding of Bubble data types and Repeating Groups
- Familiarity with custom states and conditional visibility
- Content for at least a few FAQ entries to test with
Step-by-step guide
Create the FAQ data type
Create the FAQ data type
Go to the Data tab and create a new data type called FAQ. Add fields: question (text), answer (text), category (Option Set — create a FAQCategory Option Set with values like General, Billing, Technical, Account), sort_order (number), and is_published (yes/no). The sort_order field lets you control the display order within each category. The is_published field lets admins draft entries before making them visible.
Expected result: A FAQ data type and FAQCategory Option Set exist with all necessary fields.
Build the accordion FAQ page
Build the accordion FAQ page
Go to the Design tab and create a page called faq. Add a Custom State on the page called expanded_faq (type: FAQ) to track which question is currently open. Add a Repeating Group with type FAQ, data source: Search for FAQs where is_published = yes, sorted by category then sort_order. In each cell, add the question text in bold as a clickable Text element. Below it, add the answer text inside a Group with conditional visibility: only visible when Page's expanded_faq is This cell's FAQ. This creates the accordion effect.
Pro tip: Use the Collapse when hidden checkbox on the answer Group so closed answers do not take up space in the layout.
Expected result: A FAQ page displays questions in a list, and clicking a question expands its answer below it.
Add the expand/collapse workflow
Add the expand/collapse workflow
Create a workflow: When Text Question is clicked. Add two paths. Path 1 (Only when Page's expanded_faq is Current cell's FAQ): Set state of Page expanded_faq to empty — this collapses the currently open item. Path 2 (Only when Page's expanded_faq is not Current cell's FAQ): Set state of Page expanded_faq to Current cell's FAQ — this expands the clicked item and collapses any previously open item. Add a visual indicator: a conditional on an icon element that shows a down arrow when collapsed and an up arrow when expanded.
Expected result: Clicking a question toggles its answer open or closed, and only one answer is open at a time.
Add category grouping and search
Add category grouping and search
Above the Repeating Group, add a row of category filter buttons using the FAQCategory Option Set. When a category is clicked, set a Custom State category_filter on the page. Update the Repeating Group's search to include: category = Page's category_filter (with Ignore empty constraints checked so showing all when no filter is selected). Add a Search Input above the categories. Filter the Repeating Group additionally by: question contains Search Input's value OR answer contains Search Input's value.
Expected result: Users can filter FAQs by category and search across questions and answers.
Build the admin FAQ management page
Build the admin FAQ management page
Create a page called admin-faq restricted to admin users. Add a Repeating Group showing all FAQs (including unpublished) sorted by category and sort_order. Each cell shows the question, category, sort order, published status, and Edit/Delete buttons. Add a Create New FAQ button that opens a popup with inputs for question, answer, category dropdown, sort order, and is_published checkbox. The save workflow creates a new FAQ record. The edit workflow loads the selected FAQ into the popup and uses Make changes to a thing on save. For complex help center systems, consider working with RapidDev.
Expected result: Admins can create, edit, reorder, and publish/unpublish FAQ entries from a management page.

Why it's a problem: Not using Collapse when hidden on the answer group
How to avoid: Check the Collapse when hidden checkbox on the answer Group element in the Layout properties.
Why it's a problem: Using text search without considering the 256-character indexing limit
How to avoid: For long answers, add a searchable_text field with key terms extracted, or use the answer text field with :contains which does client-side filtering.
Why it's a problem: Not adding a sort_order field
How to avoid: Add a sort_order number field and sort the Repeating Group by it so admins can control the display sequence.
Best practices
- Use Collapse when hidden on answer Groups for a clean accordion layout
- Allow only one FAQ to be expanded at a time for a focused reading experience
- Add category grouping so users can quickly find relevant questions
- Include a search bar that filters across both questions and answers
- Add sort_order for admin-controlled display sequence
- Use is_published to draft FAQs before making them visible to users
- Add structured data (FAQ schema) via an HTML element for SEO benefits

I am building a FAQ page in Bubble.io with an accordion-style expandable interface, category filtering, and search. How do I structure the data type, build the accordion with custom states, and add the search and filter functionality?
Build a FAQ page with an accordion interface. Create a FAQ data type with question, answer, category, and sort_order. Display FAQs in a Repeating Group with expand/collapse on click, category filter buttons, and a search bar. Add an admin page for managing entries.
Frequently asked questions
Can I have multiple FAQs open at the same time?
Yes. Change the expanded_faq custom state to a list of FAQs instead of a single FAQ. On click, add or remove the FAQ from the list. Set the answer visibility to when the list contains this FAQ.
How do I add FAQ schema markup for SEO?
Add an HTML element to the page with JSON-LD structured data following Google's FAQPage schema. Dynamically populate the question and answer pairs from your FAQ data type.
Can I style the accordion with animations?
Bubble's built-in animations are limited for height transitions. You can use the Animate element action for fade effects, or add CSS transitions via an HTML element for smoother expand/collapse.
How many FAQs can I display without performance issues?
Up to 50-100 FAQs work well on a single page. For larger sets, add pagination to the Repeating Group or load categories on demand.
Can I let users suggest new FAQ entries?
Yes. Add a Suggest a Question form at the bottom that creates a FAQ record with is_published = no. Admins can review and publish suggestions from the admin page.
Can RapidDev help build a help center?
Yes. RapidDev specializes in Bubble development and can help build comprehensive help centers with FAQs, knowledge base articles, video tutorials, and integrated support chat.
