hx-ext attribute enables an htmx extension for an element and all its children.
The value can be a single extension name or a comma separated list of extensions to apply.
hx-ext tag may be placed on parent elements if you want a plugin to apply to an entire swath of the DOM,
and on the
body tag for it to apply to all htmx requests.
hx-ext is both inherited and merged with parent elements, so you can specify extensions on any element in the DOM
hierarchy and it will apply to all child elements.
You can ignore an extension that is defined by a parent node using
<div hx-ext="example"> "Example" extension is used in this part of the tree... <div hx-ext="ignore:example"> ... but it will not be used in this part. </div> </div>
