Collapsed state
The accordion component has two main states: collapsed and expanded. The chevron icon at the end of the accordion indicates which state the accordion is in. The chevron points down to indicate collapsed and up to indicate expanded. Starting in a collapsed state gives the user a high level overview of the available information. Accordions begin by default in the collapsed state with all content panels closed.
Example
This is the first item's accordion body. It
is hidden by default, until the collapse plugin adds the appropriate classes
that we use to style each element. These classes control the overall
appearance, as well as the showing and hiding via CSS transitions. You can
modify any of this with custom CSS or overriding our default variables. It's
also worth noting that just about any HTML can go within the
.accordion-body, though the transition does limit overflow.

Expanded state
You can set one of the accordion items to be expanded by default. To render
an accordion that’s expanded, add the .open class on the
.accordion. For a consistent visual appearance and correct class name
switching, you also need to remove .collapsed class from the active
.accordion-button element. Note that only 1 accordion item can be expanded.

Always open
Accordion component can be configured in a way that allows users
independently expand each section of the accordion allowing for multiple sections to be
open at once. To convert accordion to a list of collapsible elements, omit the
data-bs-parent attribute on each .accordion-collapse to make
accordion items stay open when another item is opened.

Accordion as child component
The accordion component can be used as a stand alone container with its own styles
properties (e.g. border, background color etc) or within another component like card. In
certain use cases you would want to remove default styling and display accordion as
sub-component. Add
.accordion-flush to remove the default
background-color, some borders, and some rounded corners to render accordions
edge-to-edge with their parent container.
