Usage[edit]
Tags[edit]
To 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.

Weight of the option |
If you'd like some options to be shown more often than others, you can add weight to the option tags, like so:
<choose>
<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[edit]
To 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.
