The @control query marker was introduced in Semantic MediaWiki 3.0.0Released on 11 October 2018 and compatible with MW 1.27.0 - 1.31.x..

Rationale

The @control marker allows to dynamically alter a result display without the need to reload a page (where the parser cache is not in effect) and at the same time provides dynamic up-to-date results for pages with inline queries (via the #ask parser function). At the moment it necessarily uses an option which is called slider, i.e. @control=slider.

Only queries using the @deferred query marker1 support the usage of the @control query marker.

Example

Syntax

{{#ask:
 [[Category:Foo]]
 |?Bar
 |link=none
 |@deferred
 |@control=slider
}}

or

{{#ask:
 [[Category:Foo]]
 |?Bar
 |link=none
 |@deferred
 |@control=slider
}}
