...

character, one of the standard Bootstrap types c("default", "primary", "success", "info", "warning", "danger")

Value

bsplus_accordion object (htmltools::tag, <div/>)

Details

All of these functions return a bsplus_accordion object (which is also an htmltools::tag, <div/>), so you can compose an accordion by piping. There are three parts to this system:

  1. A constructor function for the accordion, bs_accordion()
  2. A function to set options for subsequent panels, bs_set_opts()
  3. A function to append a panel to the group, bs_append()

The verb append is used to signify that you can append an arbitrary number of panels to an accordion.

For the constructor, bs_accordion(), it is your responsibility to ensure that id is unique among HTML elements in your page. If you have non-unique id's, strange things may happen to your page.
