Documentation for classNames is incorrect.

[sdthornton]

Current documentation for the classNames option shows the following:

classNames: {
  // defaults
  content: 'simplebar-content',
  scrollContent: 'simplebar-scroll-content',
  scrollbar: 'simplebar-scrollbar',
  track: 'simplebar-track'
}

However, of the keys listed, only scrollbar actually functions as intended. The other three have no effect on the markup.

Per the source code type it looks like the docs could just be updated to:

classNames: {
  // defaults
  contentEl: 'simplebar-content',
  contentWrapper: 'simplebar-content-wrapper',
  offset: 'simplebar-offset',
  mask: 'simplebar-mask',
  wrapper: 'simplebar-wrapper',
  placeholder: 'simplebar-placeholder',
  scrollbar: 'simplebar-scrollbar',
  track: 'simplebar-track',
  heightAutoObserverWrapperEl: 'simplebar-height-auto-observer-wrapper',
  heightAutoObserverEl: 'simplebar-height-auto-observer',
  visible: 'simplebar-visible',
  horizontal: 'simplebar-horizontal',
  vertical: 'simplebar-vertical',
  hover: 'simplebar-hover',
  dragging: 'simplebar-dragging',
  scrolling: 'simplebar-scrolling',
  scrollable: 'simplebar-scrollable',
  mouseEntered: 'simplebar-mouse-entered',
},

This also happens with dots like gap-3.5
