Tags

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.

<choose uncached>
<option>This is the first choice.</option>
<option>This is the second choice.</option>
<option>And so on...</option>
</choose>

<choose before="{{#widget: YouTube|id=" after="}}">
<option>eR7-AUmiNcA</option><!--King of Anything-->
<option>cSCi7kCXKDA</option><!--Slipping Through My Fingers-->
<option>7n2d9XPsmmE</option><!--When Death Note Music Plays in My Car-->
</choose>

<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

To choose between one or more options, simply place each option inside the #choose: parser function, like so:

{{#choose:
 |<translate nowrap><!--T:45--> This is the first choice.</translate>
 |<translate nowrap><!--T:46--> This is the second choice.</translate>
 |<translate nowrap><!--T:47--> And so on...</translate>
}}

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.
