Accordion is a vertical stack of collapsible containers that reveal or hide sections of content.
Users can click on the accordion headers to expand or
collapse content panels, revealing more details
only when they need them.
Some accordions allow only one section to be open at at
time, while others support multiple open sections
at the same time.
Accordion panels usually have animations to aid transitions
so that the experience is smooth.
Accordions are commonly used in the following design patterns:
FAQ, Product features or specifications, Filtering & sorting.
Fun fact: The term "accordion" in UI design is inspired by the musical instrument accordion, which expands and contracts to produce sound—just like how UI accordions expand to reveal content and collapse to hide it.
