Choose supporting content
An FAQ disclosure is useful when readers have different follow-up questions. It is less useful when the collapsed panel contains the only explanation of what the page does. Keep essential instructions and the main answer visible. Reserve accordions for details that people can choose to explore after they understand the primary content.
Use the native disclosure pair
Place a summary as the label of a details element, followed by the panel content. The browser handles the basic open and closed interaction. Write the summary as a complete question, such as Are uploaded images sent to a server? A vague label like More does not help someone decide whether the panel is relevant.
Preserve an obvious interactive cue
The default marker communicates that the row expands. A custom plus or chevron can replace it visually, but the result still needs a visible focus treatment and enough space for touch interaction. Keep decorative icons out of the accessible name. Let the actual question provide the control’s meaningful label.
Let answers remain real content
Put answer text, lists and ordinary links inside the panel rather than rendering them only after the first click. For example, an image-tool FAQ can explain output format limitations and link to the converter. Native collapsed content remains part of the document; the disclosure state should not become an excuse for loading important explanations unreliably.
Be careful with exclusive behavior
Allowing several panels to stay open can help people compare answers. If the design requires an exclusive group, verify its browser support and keyboard behavior in the environments you target. Avoid unnecessarily reimplementing every toggle with JavaScript merely to force one panel closed; that can add complexity without improving the reader’s task.
Test more than the first click
Open a question with the keyboard, follow a link inside the answer, then return and close the disclosure. Try a long question at a narrow width and make sure its marker does not overlap text. Check print output as well: answers that disappear from the printed page may need a dedicated print treatment.
