The <code>{{DPL|count}}</code> and empty <code>{{DPL|offset}}</code> displays the first 3 articles from [[:Category:Fruit examples]] using [[General usage and invocation syntax#Scroll/URL syntax|Scroll/URL syntax]], and <code>scroll</code> fills the scroll/url parameter values. The <code>{{DPL|resultsheader}}</code>/footer use a helper template ([[Template:DPL3 scroll]]) to create scroll navigation, composed of [[mw:Help:Magic_words#Statistics|magic word]] (<code><nowiki>{{PAGESINCATEGORY:</nowiki>''Category''}}</code>) and some parameters are fed to that template, so it can determine total pages, count, and amount of offset. <code>{{DPL|allowcachedresults}}</code> prevents caching, to prevent the need for manual purge. |
|||
This selects pages from [[:Category:Fruit examples]] and sets the count to display the first 3 articles in that category (using a URL variable instead of a number, so the count can be overwritten as needed). The <code>scroll</code> parameter enables scrolling through the category result set, and also enables support for the use of URL variables to change the DPL3 query. The <code>resultsheader</code> displays text that gives the <code>DPL_count</code> variable value, and the current {{DPL|offset}} value. |
|||
Adding <code>&DPL_offset=3</code> to the end of the ([[mw:Manual:Parameters_to_index.php|index.php]]-style) URL seen below, causes the contents of the DPL3 query displayed on-page to change; the next 3 results in the result set are displayed. |

Example
The count and empty offset displays the first 3 articles from Category:Fruit examples using Scroll/URL syntax, and scroll fills the scroll/url parameter values. The resultsheader/footer use a helper template (Template:DPL3 scroll) to create scroll navigation, composed of magic word ({{PAGESINCATEGORY:Category}}) and some parameters are fed to that template, so it can determine total pages, count, and amount of offset. allowcachedresults prevents caching, to prevent the need for manual purge.
{{#dpl:execandexit=geturlargs}}
{{#dpl:
|category = Fruit examples
|count = {%DPL_count:3%}
|offset = {%DPL_offset:0%}
|scroll = yes
|resultsheader = ²{DPL3 scroll¦total={{PAGESINCATEGORY:Fruit examples|R}}¦offset={%DPL_offset:0%}¦count={%DPL_count:3%}¦page={{FULLPAGENAME}}}²\n
|resultsfooter = ²{DPL3 scroll¦total={{PAGESINCATEGORY:Fruit examples|R}}¦offset={%DPL_offset:0%}¦count={%DPL_count:3%}¦page={{FULLPAGENAME}}}²\n
|allowcachedresults = false
}}
Result
{{#dpl:execandexit=geturlargs}} {{#dpl: |category = Fruit examples |count = {%DPL_count:3%} |offset = {%DPL_offset:0%} |scroll = yes |resultsheader = ²{DPL3 scroll¦total=7¦offset={%DPL_offset:0%}¦count={%DPL_count:3%}¦page=Examples/Parameter: scroll (example 2)}²\n |resultsfooter = ²{DPL3 scroll¦total=7¦offset={%DPL_offset:0%}¦count={%DPL_count:3%}¦page=Examples/Parameter: scroll (example 2)}²\n |allowcachedresults = false }}
