An accordion element holds multiple, collapsible item elements in a vertical stack, each with different content. Accordions can be configured so that only one item is expanded at a time, or so that multiple containers can be expanded simultaneously. Site visitors can click an accordion item's title to expand or collapse the item. ![Example of an accordion element rendered on a webpage, with one expanded item and three collapsed items](https://wixmp-833713b177cebf373f611808.wixmp.com/images/velo-images/media_accordion.png). With Velo, you can scroll to an accordion and modify accordion styles.
