Here is a method that allows the overall table header to wrap anywhere as needed. It is using a column header in the wikitext instead of caption wikitext. It is basically a wrapper. Any table can be placed inside without alteration. |

![]() | This help page is a how-to guide. It explains concepts or processes used by the Wikipedia community. It is not one of Wikipedia's policies or guidelines, and may reflect varying levels of consensus. |
A collapsible element contains a toggle a reader can use to show or hide the element's content. Elements are made collapsible by adding the mw-collapsible
class, or alternatively by using the {{Collapse}}
template, or its variants {{Collapse top}}
and {{Collapse bottom}}
.
Use of these features in article content is governed by the guidelines Wikipedia:Manual of Style § Scrolling lists and collapsible content generally, and more specifically by Wikipedia:Spoiler.
Collapsible tables
[edit]The mw-collapsible
class can make any element collapsible, but tables are particularly simple to make collapsible. Adding the mw-collapsible
class to a table automatically positions the toggle, and selects which parts to collapse.
A common use is to make a collapsible layout table, which always displays an introduction or summary, but hides the rest of the content from immediate view. The introduction or summary is in the first row, and the content is in subsequent rows. The content is then easily accessible by using the 'show' button.
In the examples below, the use of the class wikitable
is merely for appearance; it is not needed for mw-collapsible
to function.
Code entered | Output produced | ||
---|---|---|---|
{| role="presentation" class="wikitable mw-collapsible"
| <strong>Lorem ipsum</strong>
|-
| Lorem ipsum dolor sit amet
|}
|

More complex data tables can also be collapsible.

Collapsing by default
[edit]Just using the mw-collapsible
class leaves the element expanded by default, but it can be collapsed by the reader. It is also possible to make the element collapsed by default, and optionally expanded by adding other classes along with mw-collapsible
. There are several methods for doing this, depending on the situations in which you want the element to collapse. However, content should not be collapsed by default per MOS:DONTHIDE.
"mw-collapsed"
[edit]Adding the mw-collapsed
class will cause the element to always be initially collapsed, no matter what happens around it. It is the simplest method for doing so. Using the examples above:
Code entered | Output produced | |||||||||
---|---|---|---|---|---|---|---|---|---|---|
{| role="presentation" class="wikitable mw-collapsible mw-collapsed"
| <strong>Lorem ipsum</strong>
|-
| Lorem ipsum dolor sit amet
|}
|
| |||||||||
{| class="wikitable mw-collapsible mw-collapsed"
|+ class="nowrap" | Winter Olympic Games
|-
|
! scope="col" | City
! scope="col" | Country
|-
! scope="row" | 1994
| Lillehammer || Norway
|-
! scope="row" | 1998
| Nagano || Japan
|}
|
|
"autocollapse"
[edit]Adding the autocollapse
class causes an element to collapse if there are 2 or more collapsible elements on the page. The example below, therefore, collapses because there are numerous collapsible elements on this page.
Code entered | Output produced | ||
---|---|---|---|
{| role="presentation" class="wikitable mw-collapsible autocollapse"
| <strong>Lorem ipsum</strong>
|-
| Lorem ipsum dolor sit amet
|}
|
|
"innercollapse" and "outercollapse"
[edit]Using this pair of classes, it is possible to make an element collapsed by default only when it is contained within a particular outer element. An element with the mw-collapsible
and innercollapse
classes is collapsed by default if it is contained within an element with the outercollapse
class; otherwise, it is uncollapsed by default. This is mainly useful for templates, which are often nested.
Code entered | Output produced | ||||
---|---|---|---|---|---|
{| role="presentation" class="wikitable mw-collapsible innercollapse"
| This <code>innercollapse</code> element is
|-
| <em>uncollapsed</em> by default
|}
<div class="wikitable outercollapse" style="padding:1em; background:#ccc;">
This is an element with the <code>outercollapse</code> class.
{| role="presentation" class="wikitable mw-collapsible innercollapse"
| This <code>innercollapse</code> element is
|-
| <em>collapsed</em> by default
|}
</div>
|
This is an element with the

Other notes
[edit]Tables with captions
[edit]A table without a caption will collapse to its first row. A table with a caption will collapse to its caption, with no rows, therefore no width. Use class="nowrap"
or {{nowrap}}
to keep the caption from being squeezed into a vertical column when the table is collapsed.
Code entered | Output produced | ||||||
---|---|---|---|---|---|---|---|
{|class="wikitable sortable mw-collapsible"
|+ class="nowrap" | Somewhat long table caption
! Name !! Score
|-
| John || 59
|-
| Bob || 72
|}
|
|
Next example uses {{nowrap}}
where the end brackets become the wrap point. <style=max-width:Xem;
will not work.
Code entered | Output produced | ||||||
---|---|---|---|---|---|---|---|
{|class="wikitable sortable mw-collapsible"
|+ {{nowrap|A longer table caption needs to wrap}} for cell phones, etc.
! Name !! Score
|-
| John || 59
|-
| Bob || 72
|}
|
|
Sortable tables
[edit]Collapsible tables can be combined with the sortable tables functionality without difficulty. However, because the hide/show button is placed with mw-collapsible
in the right header cell, its positioning can look a bit peculiar if the cell is not wide enough:
Code entered | Output produced | ||||||
---|---|---|---|---|---|---|---|
{|class="wikitable mw-collapsible sortable" style="width:5em"
<!--table width too narrow, on purpose here-->
|-
! Name !! Score
|-
| John || 59
|-
| Bob || 72
|}
|
|
A possible alternative is to add a caption over the table. See the following example.
Code entered | Output produced | ||||||
---|---|---|---|---|---|---|---|
{|class="wikitable sortable mw-collapsible"
|+ class="nowrap" | Caption
! Name !! Score
|-
| John || 59
|-
| Bob || 72
|}
|

Limitations
[edit]- This functionality requires the end-user's browser to have JavaScript enabled. If JavaScript is disabled, the default behaviour is to show the content.
- It doesn't work on mobile browsers (or desktop browsers in mobile mode) either.
