Capital Framework expandables
This component can be used by itself, but it was made for Capital Framework, a front end framework developed at the Consumer Financial Protection Bureau.
How to use this component
Detailed instructions can be found at the Capital Framework documentation site.
NOTE: Be sure to run the Less files through Autoprefixer, or your compiled Capital Framework CSS will not work perfectly in older browsers.
