This is the documentation for the Joomla 3 version of Sliders.
There is no Joomla 4+ version of Sliders.
However you can use the Tabs & Accordions for Joomla 4+.
Sliders for Joomla 3 is based on the Bootstrap accordion/collapse functionality, so it uses and needs the Bootstrap 2 framework (styles and scripts) that comes with Joomla core.
This means that Sliders will only function correctly if your template allows the Bootstrap 2 framework to be loaded and does not cause conflicts with the jQuery and bootstrap javascripts.

Sliders is a Joomla! system plugin that allows you to display content in sliders (also known as "collapses" or "accordions").

It also comes with an editor button plugin

With Sliders you can make content sliders anywhere in Joomla! - including within articles, inside modules, or even 3rd party components and template overrides.
