Template:Image key

Template documentation[view] [edit] [history] [purge]

The image key template is intended to help create lists of keys in images. These keys will display in 2 columns. The syntax is trivial: just add the list using the same syntax as Template:Unbulleted list!

Use

Note: This template may be used only within the caption parameter of an image. It won't work in a caption parameter of an infobox.

{{image key
|list type=
|
|
|
...
}}

Prefer the redirect {{legend-col}} when this template is being used to support the use of {{legend}}.

Parameters

|list type=

Defines a list type for the template. Can be one of the values ordered, bulleted, unbulleted (synonym plainlist). An ordered list is numbered, bulleted are basic lists, and unbulleted display nothing (i.e., are "plain lists").

|<N>=

A list item. If there is an equal sign in the list item, add it as the numbered item e.g. |1=list item with equals sign.

|thumb size=

Optional.

|thumb size=wide Adds a 3rd column. Use only for "wide" images.

|thumb size=narrow Removes one column to display 1 column only. Use only for "narrow" images.

Most thumbnails these days use |upright=, so these are qualitative rather than quantitative directions for use of |wide= and |narrow=.
