Usage
editTags
editTo choose between one or more options, simply place each option inside an <option>
tag which are themselves placed inside <choose>
tags, like so:
<choose>
<option>This is the first choice.</option>
<option>This is the second choice.</option>
<option>And so on...</option>
</choose>
From each set of <choose>
tags, precisely one <option>
tag will be selected at random, and its contents shown.
Anything can be placed inside of option tags: links, images, even templates.
You can also have what is placed inside the option tags be sent as an argument to a template with the <choicetemplate>
tag, e.g.:
<choose>
<option>Template:Featured article/Elephant</option>
<option>Template:Featured article/Giraffe</option>
<option>Template:Featured article/Rhinoceros</option>
<choicetemplate>PageWithEditButton</choicetemplate>
</choose>
You could then create a [[Template:PageWithEditButton]] with these contents:
[{{canonicalurl:{{{1}}}|action=edit}} Edit] {{{{{1}}}}}
This is useful if you want to set up randomly rotating featured articles and have an edit button to allow the user to edit the featured article blurbs.

<option weight="2">This option will be shown twice as often as a normal option.</option>
<option>By default, options have a weight of 1.</option>
<option weight="1.5">This option also has a weight of 1. Fractional portions are ignored.</option>
</choose>
Parser function
editTo choose between one or more options, simply place each option inside the #choose:
parser function, like so:
{{#choose: |This is the first choice. |This is the second choice. |And so on... }}
From each choice divided by a pipe, precisely one choice will be selected at random, and its contents shown. Anything can be placed inside: links, images, even templates.
