This template is designed for use in WikiProject banners, and provides an easy way to construct a bespoke class mask. The ''class'' parameter must be passed to the template as the first unnamed parameter.

===Implementation in [[Template:WPBannerMeta]]===
The template provides the default class masks for WikiProject's quality scales, and is also used by the majority of projects which use a custom class mask. It can be used in two different ways:
* with {{para|QUALITY_SCALE|subpage}} and placed on the /class subpage of the WikiProject's banner template. In this case, specific guidance on how the template works with the chosen parameters is displayed on this page.
* with {{para|QUALITY_SCALE|inline}} and placed directly inside the ''class'' parameter.

=== Use on subpages ===
When used on a /class subpage (e.g. with {{para|QUALITY_SCALE|subpage}}) the template should be called in the following way:
<pre>{{class mask<noinclude>/templatepage</noinclude>|{{{class|}}}
 |topic=
 |optional parameters
}}</pre>
This allows the [[Template:Class mask/templatepage|/templatepage]] to be displayed which provides useful documentation and category prompts on the subpage.
* the ''topic'' parameter defines the main naming scheme of the assessment categories used by the project and is used to check the existence of the categories that are required. For example, if your project uses categories such as [[:Category:B-Class mathematics articles]], etc. then set {{para|topic|mathematics}}.
** if the template uses taskforces, parameters ''topic1'', ''topic2'', ''topic3'', ''topic4'' and ''topic5'' can be used to check for the necessary categories.
 
Neither of the above are required for the {{para|QUALITY_SCALE|inline}} version.

=== Inline use ===
When used "inline" (e.g. with {{para|QUALITY_SCALE|inline}}), the call to /templatepage and the ''topic'' parameters are not required, and the template should be called in the following way:
<pre>{{class mask |{{{class|}}} |optional parameters }}</pre>
Bear in mind that if the banner uses any hooks (e.g. the [[Template:WPBannerMeta/hooks/taskforces|taskforce hook]]), you will need to set the options each time ''class'' is used. Therefore, the subpage method may be more useful in these cases.

=== Optional parameters ===
* {{para|FQS}} – if set to <code>yes</code>, switches on seven additional classes: Category; Disambig; Draft; File; Portal; Project; and Template (FQS stands for Full Quality Scale). Individual classes may then be switched off as desired using the following seven parameters:
*{{para|category}}
*{{para|disambig}}
*{{para|draft}}
*{{para|file}}
*{{para|portal}}
*{{para|project}}
*{{para|template}} – when {{para|FQS|yes}} is present, setting one or more of these seven to <code>no</code> will switch off that class; when {{para|FQS|yes}} is absent, setting one or more to <code>yes</code> will switch on that class.
*{{para|fa}}
*{{para|fl}}
*{{para|a}}
*{{para|ga}}
*{{para|b}}
*{{para|c}}
*{{para|start}}
*{{para|stub}}
*{{para|list}} – if one or more of these nine is set to <code>no</code>, the class will be switched off. The default is <code>yes</code> regardless of the {{para|FQS}} setting.
*{{para|book}}
*{{para|fm}}
*{{para|redirect}} – if one or more of these three is set to <code>yes</code>, the class will be switched on. The default is <code>no</code> regardless of the {{para|FQS}} setting.
* {{para|forceNA}} - if set to <code>yes</code>, will automatically classify pages tagged as {{para|class|NA}} depending on the namespace of the page. The default setting is <code>no</code>.
* {{para|b1}}, {{para|b2}}, {{para|b3}}, {{para|b4}}, {{para|b5}}, {{para|b6}} - if the B-class checklist is used, these parameters must be passed through.

=== The lowercase parameter syntax ===
Add a class in '''lowercase''' as the name of a parameter followed by the value "yes". For example,
<pre>|redirect=yes</pre>
would add the Redirect-class. This is the simplest way of adding a class but has the following two limitations:
* The name of the class must have an initial capital letter and all following letters in lowercase. In other words, the capitalisation must be of the form Xxxxxx.
* It is not possible to use this method to add a shortcut or alternative alias for a different class, for example "Cur" for Current-class.
If either of these are required, the uppercase parameter syntax must be used (see below).

If {{para|FQS|yes}} is used, then a value of "no" may be used to switch off that individual class. Thus, on a /class subpage:
<pre>{{class mask<noinclude>/templatepage</noinclude>|{{{class|}}}
 |topic=physics
 |FQS=yes
 |portal=no
}}</pre>
would support six of the seven additional classes listed above and would ''not'' support Portal-class.

=== The UPPERCASE parameter syntax ===
Add a class in '''uppercase''' as the name of a parameter followed by the ''exact name'' of the class (including the required case) as the value of the parameter. For example,
<pre>|SL=SL</pre>
would add SL-class and
<pre>|CHEESECAKE=CheeseCake</pre>
would add CheeseCake-class.

You can use this method to add a shortcut or alias for a class. For example,
<pre>|bplus = yes
|B+ = Bplus</pre>
would have the effect that an input of either B+ or Bplus would result in Bplus-class.

=== Example 1: subpage ===
The following code is placed in the banner template:
<pre>
|QUALITY_SCALE=subpage
 |class={{{class|}}}
</pre>
and on the /class subpage (for example [[Template:WikiProject Zimbabwe]] uses the subpage [[Template:WikiProject Zimbabwe/class]]), the following code is used:
<pre>
{{class mask<noinclude>/templatepage</noinclude>|{{{class|}}}
 |topic=Zimbabwe
 |FQS=yes
 |redirect=yes
}}
</pre>
In this case all six of the "extended" quality classes are used, plus the additional Redirect-class. Because the {{para|topic}} parameter is set, specific documentation will be displayed on the /class subpage.

=== Example 2: inline ===
The following code is placed in the banner template:

<pre>
|QUALITY_SCALE = inline
 |class={{class mask |{{{class|}}} |FQS=yes |redirect=yes |fm=yes}}
</pre>

Now the extended quality classes are used, plus the additional Redirect and FM classes.

=== Subtemplates ===
* [[Template:Class mask/b|/b]] - the mask for B-checklist parameters
* [[Template:Class mask/sandbox|/sandbox]] - the template sandbox, used for experimentation
* [[Template:Class mask/templatepage|/templatepage]] - the documentation that is displayed on /class subpages
** [[Template:Class mask/templatepage/row|/templatepage/row]] - used by /templatepage
* [[Template:Class mask/doc|/doc]] - the documentation you are reading now
** [[Template:Class mask/doc/custom|/doc/custom]] - for information on building your own class mask

=== Uses ===
* [{{fullurl:Special:WhatLinksHere/Template:Class mask/templatepage|&hidelinks=1&hideredirs=1}} This] shows all /class subpages which use this template.
