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


If you use a bs_accordion_sidebar(), you will have to call the function use_bs_accordion_sidebar() somewhere in your UI. This attaches some JavaScript needed for your accordion sidebar to work properly.

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

  1. A constructor function for the accordion-sidebar, bs_accordion_sidebar()
  2. A function to set options for subsequent panels, bs_set_opts()
  3. A function to append a panel-set to an accordion-sidebar, bs_append()

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

For the constructor, bs_accordion_sidebar(), 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.
