Sample contents text

 should always be placed on its own line.

Parameters
This template takes the following parameters, all of which are optional. They are case-sensitive. Those that take CSS measurements require them in CSS format (e.g.   not  .


 * 1 (or first unnamed parameter), title, reason, header, heading
 * Will give the collapsed box a title, which occurs on the same line as the show link and is always visible. It defaults to "Extended content".
 * For example,   or <tvar|2> </>. Note: The shorter, unnamed markup will not work if the title value contain an equals (<tvar|1> </>) character.


 * yes
 * Will display a default warning line under the main title which reads "The following is a closed debate. "
 * Any non-empty value supplied to this parameter will have this effect (i.e. <tvar|1>no</> will not work as expected).


 * 2 (or second unnamed parameter)
 * This is optional warning-line text. It will override the standard warning line above; it is not necessary to also use <tvar|1>yes</> in this case, though doing so is harmless.


 * yes
 * Will align the title along the left margin (in RTL languages, along the right margin instead).
 * By default, text is centered, specifically between the left edge of the green box and the left edge of the "show" link.
 * Any non-empty value supplied to this parameter will have this effect (i.e. <tvar|1>no</> will not work as expected).


 * yes
 * Will leave the material uncollapsed with the border and coloring. Default is to collapse the material.
 * Any non-empty value supplied to this parameter will have this effect (i.e. <tvar|1>no</> will not work as expected).


 * bg
 * Sets the background color of the title of the collapsible bar. Defaults to "<tvar|1>#F8FCFF</>", a whitish color.  Named colors are listed at List of colors.
 * For example, <tvar|1> </> or <tvar|2> </> (numeric HTML color codes require the leading <tvar|H> </>).


 * fc
 * Sets the font color of the title of the collapsible bar. Defaults to "<tvar|1>black</>".
 * See <tvar|bg>bg</>, above, for details on color options.


 * border
 * Sets the width of the border line on the collapsed material. Defaults to <tvar|1> </>.
 * For example, <tvar|1> </>; going much thicker than this is not very useful.


 * b-color
 * Sets the border color. Defaults to <tvar|1> </> (<tvar|2> </>).
 * See <tvar|bg>bg</>, above, for details on color options.


 * padding
 * Sets the padding (distance from borders) on the collapsed material inside the colored area. Defaults to <tvar|1> </>.


 * width
 * Sets the width of the overall template relative to the page (or a block element containing the collapse box). This should virtually always be given as a percentage, e.g. <tvar|1>50%</>, or in relative <tvar|2> </> units, e.g. <tvar|3>30em</>.  Pixel-based values should be avoided, as they are effectively meaningless – the result will be different depending on each user's browser and local CSS settings (which browser and operating system it is, zoom level, font sizes, etc.).


 * border2
 * Sets the properties of the border of the box that appears when template is expanded. Defaults to <tvar|1> </> (there is no provision to change from a solid line).
 * For example, <tvar|1> </> (only width or color will be changed if only one value is supplied).
 * See <tvar|bg>bg</>, above, for details on color options.


 * bg2
 * Sets the background color of the box that appears when template is expanded; defaults to <tvar|1> </> (<tvar|2> </>).
 * See <tvar|bg>bg</>, above, for details on color options.


 * indent
 * Indents the box from the left of the page. Defaults to no indentation.  Each <tvar|1> </> in talk page markup is approximately equivalent to <tvar|2> </> of indent (e.g., to match <tvar|3> </> indentation level, use <tvar|4>6.4em</>.  You can also use a percentage value.
 * Pixel-based values should be avoided (see <tvar|1>width</>, above, for the reason).
