This is the example preloaded for testing, press "Show Preview" to see
the example working (at the bottom of the page). If you save this page,
it saves as a new section at the bottom of your '''User:Username/Sandbox'''
-->
==Example==
This selects pages from [[:Category:Fruit examples]]. The <code>{{DPL|count}}</code> displays the first article using {{DPL|URL parameters}}, and an empty <code>{{DPL|offset}}</code> also using that syntax; setting both using scroll/url syntax, allows their query values to be overwritten by URL. The <code>{{DPL|scroll}}</code> parameter fills the scroll/url parameter values. The <code>{{DPL|resultsheader}}</code> displays header text to show the count and current result start number. Setting <code>{{DPL|allowcachedresults}}=''false''</code> prevents caching, so result changes are immediately seen when the URL is changed, without the need to manually purge the MediaWiki cache.
The result is a static display of the first 3 pages, but their display offset (page to start at) and count can be ''overwritten'' just by adding two DPL3-specific URL parameters <code>&DPL_count=1&DPL_offset=1</code> to the end of the ([[mw:Manual:Parameters_to_index.php|index.php]]-style) URL. If you '''copy/paste the URL into your browser's URL bar''', you can see the next result is loaded from the URL parameters:
* <code><nowiki>https://dpl3.miraheze.org/w/index.php?title=Criteria_for_page_selection/Parameter:_scroll_(example_1)&DPL_count=1&DPL_offset=1</nowiki></code>
<pre>
{{#dpl:execandexit=geturlargs}}
{{#dpl:
|category = Fruit examples
|count = {%DPL_count:1%}
|offset = {%DPL_offset:0%}
|scroll = yes
|resultsheader = Showing {%DPL_count:1%} pages starting from page ²{#expr:{%DPL_offset%} + 1}²:\n
|allowcachedresults = false
}}
</pre>
==Result==
