Template:Collapsed infobox section begin/doc

This template is used with to create a collapsed section in an infobox. This is not the same as hidden, which can be used to collapse an infobox, or collapsible list, which collapses a single list within an infobox.

Usage
Place before the first line of the collapsed section (typically in the caption, for an infobox with an image), and place  after the last line of the collapsed section (typically just after the website or footnotes).

Parameters
The template has one optional unnamed parameter which is the title used for the collapsed section.

If omitted, the template will use the default heading, " ".

The template has two optional named parameters for adjusting the style. To change the style for the section title, use titlestyle. To change the style for the collapsed table, use style.

Setting yes or yes will reduce the margin at the bottom of the section.

Setting yes will inject and  tags to fix "linter errors". Typically, this is necessary when the or  is placed inside of an  caption.

Setting yes will inject a tag before the content in order to fix a different Linter error that can occur when this template is used inside other infobox parameters.

If the hidden content spans three or more columns, set 3 or the respective number of columns.

Warnings
If either the begin or end templates are not properly transcluded, disaster may strike, causing the infobox to either swallow the article (missing the end template), or terminate unexpectedly (missing the begin template).

When biographical infoboxes include the subject's signature, the signature cannot be inside the collapsed portion. If either signature or signature_alt are included between the begin and end templates, the infobox will swallow the article.

As with all collapsed content, if there are references to citations inside collapsible sections, readers cannot jump to the location of the reference using the backlinks (^ or n$a b c ...$) at the citation. Backlinks will only work when the collapsible section(s) is/are expanded. The same is true for citations within a collapsed collapsible list or hidden template or any collapsed content.
