hx-ext

The 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.

The 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.

Notes

• 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.
