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-extis 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.
