Editing Template:Infobox/doc (section)

==== Hiding headers when all its data fields are empty ====
You can also make headers automatically hide when their section is empty (has no data-row showing).

Consider this situation:
{{Infobox
 | title   = Example: header with & without data
 | headerstyle = background:lightgrey

 | header1 = Header1 with empty section
 |  label2 = label2 text |   data2 =
 |  label3 = label3 text |   data3 =
 |  label4 = label4 text |   data4 =

 | header5 = Header5 with data below
 |  label6 = label6 text |   data6 = Some value
}}
<syntaxhighlight lang="wikitext" style="overflow:auto">
{{Infobox
 | title   = Example: header with & without data
 | headerstyle = background:lightgrey

 | header1 = Header1 with empty section
 |  label2 = label2 text |   data2 =
 |  label3 = label3 text |   data3 =
 |  label4 = label4 text |   data4 =

 | header5 = Header5 with data below
 |  label6 = label6 text |   data6 = Some value
}}
</syntaxhighlight>{{clear}}

If you want hide the header when no {{para|data''N''}} values are present, use '''{{para|autoheaders|y}}''':

{{Infobox
 | title   = Example: header with & without data
 | autoheaders = y
 | headerstyle = background:lightgrey

 | header1 = Header1 with empty section
 |  label2 = label2 text |   data2 =
 |  label3 = label3 text |   data3 =
 |  label4 = label4 text |   data4 =

 | header5 = Header5 with data below
 |  label6 = label6 text |   data6 = Some value
}}

<syntaxhighlight lang="wikitext" style="overflow:auto">
{{Infobox
 | title   = Example: header with & without data
 | autoheaders = y
 | headerstyle = background:lightgrey

 | header1 = Header1 with empty section
 |  label2 = label2 text |   data2 =
 |  label3 = label3 text |   data3 =
 |  label4 = label4 text |   data4 =

 | header5 = Header5 with data below
 |  label6 = label6 text |   data6 = Some value
}}
</syntaxhighlight>{{clear}}

So, header1 will be shown if any of item1, item2, or item3 is defined. If none of the three parameters are defined the header won't be shown and no empty row appears before the next visible content.

Note: if the data has empty css elements, like {{para|data|2=&lt;span style="background:yellow;">&lt;/span>}}, this will be treated as non-empty (having data).

If {{para|autoheaders|y}} but there are items that you ''do not'' want to trigger a header, place {{para|headerX|_BLANK_}}. This will serve as an empty header and separate it from the subsequent items.

{{Infobox
 | title   = Example: blank header with & without data
 | autoheaders = y
 | headerstyle = background:lightgrey

 | header1 = Header1 with empty section
 |  label2 = label2 text |   data2 =
 |  label3 = label3 text |   data3 =
 |  label4 = label4 text |   data4 =

 | header5 = _BLANK_
 |  label6 = label6 text |   data6 = Some value, but does not trigger header1 or show header5
}}

<syntaxhighlight lang="wikitext" style="overflow:auto">

</syntaxhighlight>{{clear}}
