This template applies Module:Hatnote group to merge hatnotes it is given as input; this has the net effect of making them formatted inline relative to one another. For example:

{{about|USE1||PAGE1}}
{{redirect|REDIRECT|USE2|PAGE2}}

would normally display as:

but, when wrapped in this template:

{{hatnote group|
{{about|USE1||PAGE1}}
{{redirect|REDIRECT|USE2|PAGE2}}
}}

displays as

Technically, it changes the hatnotes by converting their div wrappers into spanwrappers, wrapping the group in a new hatnote div, and migrating classes appropriately. Classes are migrated to the appropriate span, unless every hatnote in the group includes that class, in which case the class will be migrated to the new div wrapper. For example:

{{hatnote|extraclasses=example demonstration |Hatnote 1}}
{{hatnote|extraclasses=example |Hatnote 2}}
{{hatnote|extraclasses=example |Hatnote 3}}

would normally be rendered to:

<div role="note" class="hatnote navigation-not-searchable example demonstration">Hatnote 1</div>
<div role="note" class="hatnote navigation-not-searchable example">Hatnote 2</div>
<div role="note" class="hatnote navigation-not-searchable example">Hatnote 3</div>

but, when wrapped in this template, becomes:

<div role="note" class="hatnote navigation-not-searchable example">
<span class="demonstration">Hatnote 1</span> 
<span>Hatnote 2</span> 
<span>Hatnote 3</span> 
</div>
