Editing DPL3/Parameters: Controlling output format (section)

===headingmode===

{{DPL parameter
 |name   = headingmode
 |purpose= To control the output of the headings in a DPL with complex/multi-parameter {{dpl3|ordermethod}}. (No effect with single-param ordermethods.) For {{dpl3|ordermethod|=''method1,method2,...''}}, ''method1'' is used for headings. E.g. {{dpl3|headingmode}} affects category headings in {{dpl3|ordermethod|=category,title}} (2-param ordermethod). See also {{dpl3|headingcount}}
}}

Syntax:

{{DPL syntax|headingmode=''modename''}}

''modename'' can be one of:
* ''none'' &mdash; headings are not displayed, no heading &mdash; '''(default)'''
* ''unordered'' &mdash; outputs an unordered list &mdash; HTML tag {{tt|ul}}
* ''ordered'' &mdash; outputs an ordered list &mdash; HTML tag {{tt|ol}}
* ''definition'' &mdash; outputs a definition list &mdash; HTML tag {{tt|dl}}
* ''H2'' &mdash; outputs sections &mdash; HTML tags {{tt|H2}} {{red|Currently broken}}
* ''H3'' &mdash; outputs sections &mdash; HTML tags {{tt|H3}} {{red|Currently broken}}
* ''H4'' &mdash; outputs sections &mdash; HTML tags {{tt|H4}} {{red|Currently broken}}

Example:
<!-- originally, category=Africa|Europe  -->
<pre><nowiki>
<dpl>
  category=Terraria Wiki|Community
  notcategory=Games
  nottitlematch=%d%|Disambiguations
  count=7
  ordermethod=category,title
  headingmode=definition
  mode=ordered
</dpl>
</nowiki></pre>
This list will output pages that belong to one of the categories Terraria Wiki, Community in a list similar to this (HTML source). The categories are listed in sorted order, and the titles are replaced with the appropriate links ({{dpl3|nottitlematch}} and {{dpl3|count}} are simply used to reduce the output size):
{|
! '''(HTML) Output''' !! '''Actual Output'''
|- style="vertical-align:top;"
|<pre><nowiki>
<dl>
  <dt>Category</dt>
  <dd>
    <ol>
      <li>Page1</li>
      <li>Page2</li>
    </ol>
  </dd>
</dl>
</nowiki></pre>
|
<dpl>
  category=Terraria Wiki|Community
  notcategory=Games
  nottitlematch=%d%|Disambiguations
  count=7
  ordermethod=category,title
  headingmode=definition
  mode=ordered
</dpl>
|}

Headingmode can be used with multi-column output but the length of the columns may in this case vary more than you would expect.
