This template creates a dynamic navigation box using style sheet declarations in MediaWiki:Common.css and Javascript code in MediaWiki:Common.js. It displays the first parameter (the heading) with a [show] link on the right. If [show] is clicked by the user, the second parameter (the body) is displayed below the heading and the [show] link becomes [hide]. Clicking on [hide] then hides the body again and the [hide] link becomes [show] again.

Example with unnamed parameters

{{लुप्त|Title text here|Body text line 1<br/>Body text line 2}}

Example with mix of named & unnamed parameters

{{लुप्त|Title text here|Body text line 1<br/>Body text line 2|bg1=#ccccff|ta2=center}}

Example with named parameters & CSS

{{लुप्त
| headercss = background: #ccccff; font-size: 110%; width: 50%;
| contentcss = text-align: center; font-size: 110%; width: 50%;
| header = Title text here
| content = Body text line 1<br/>
Body text line 2<br/>

}}
