The slider macro allows embedding tiddlers within another tiddler, with the option to toggle the visibility of the transclusion content:
<<slider cookie tiddler label tooltip>>
  • cookie: variable to save the state of the slider (e.g. chkFooSlider)
  • tiddler: name of the tiddler to include in the slider
  • label: title text of the slider
  • tooltip: tooltip text of the slider

For example: 
<<slider chkTestSlider [[OptionsPanel]] "Options" "Open advanced options">>
