How to Set Up a Dynamic FAQ Section in FlutterFlow

In Firestore, create a collection called faq_items with fields: question (String), answer (String), category (String — e.g., Billing, Account, Product, Shipping), order (Integer — for display sorting), and isPublished (Boolean, default true). Add 8-10 test FAQ entries across different categories, assigning sequential order values (1, 2, 3...). Set Firestore rules to allow public reads (anyone can view FAQs) and restrict writes to admin users only. The isPublished field lets admins draft new FAQs without showing them immediately.

Create a new Component called FAQSection. Add a Component Parameter called categoryFilter of type String (optional, default empty). Inside the Component, place a ListView bound to a Backend Query on faq_items where isPublished == true, ordered by order ascending. If categoryFilter is not empty, add a query filter: where category == categoryFilter. For each list item, use the Expandable widget (FlutterFlow's built-in accordion). Set the collapsed child to a Row with a Text widget showing the question in bodyLarge bold and an Icon (Icons.expand_more). Set the expanded child to the same header Row (with Icons.expand_less) plus a Padding Container with a Text widget showing the answer in bodyMedium with secondary text color. The Expandable widget provides smooth height animation automatically.

Above the ListView inside the FAQSection Component, add a ChoiceChips widget with options: All, Billing, Account, Product, Shipping (matching your faq_items categories). Bind the selected value to a Component State variable selectedCategory (String, default All). Modify the Backend Query on the ListView: add a conditional filter — if selectedCategory != All, filter where category == selectedCategory. When the Component receives a categoryFilter parameter that is not empty, hide the ChoiceChips using Conditional Visibility (only show when categoryFilter is empty) and use categoryFilter as the fixed filter instead. This way, the standalone FAQ page shows all categories with chips, while embedded instances show only their relevant category.

Above the ChoiceChips, add a TextField with a prefix Icon (Icons.search) and hint text 'Search FAQs...'. Bind its value to a Component State variable searchQuery (String). Modify the Backend Query to add a filter: if searchQuery is not empty, apply where question >= searchQuery AND question <= searchQuery + '\uf8ff'. This is Firestore's prefix matching pattern — it finds questions that start with the typed text. For better search coverage, also create a Custom Function filterBySearch that client-side filters the query results checking if the question OR answer contains the searchQuery (case-insensitive). Wrap the ListView in a Column and apply the Custom Function filter to the query results before binding to the list.

On your product page, drag the FAQSection Component from the component library and set the categoryFilter parameter to 'Product'. On your checkout page, set categoryFilter to 'Shipping'. On your account settings page, set categoryFilter to 'Account'. For a dedicated FAQ page (e.g., /faq), add the FAQSection Component with no categoryFilter parameter — this shows all categories with the ChoiceChips filter visible. Each embedded instance automatically queries only the relevant FAQs, and admins can add or update questions in Firestore without republishing the app. The Component is fully self-contained with its own query, state, and UI.
