The hx-ext attribute in htmx enables one or more htmx extensions for an element and all its children. You can also \
use this attribute to ignore an extension that is enabled by a parent element."""
+++
The `hx-ext` attribute enables an htmx [extension](https://htmx.org/extensions) 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.
* You can ignore an extension that is defined by a parent node using `hx-ext="ignore:extensionName"`
```html
<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>
```
```html
<body hx-ext="preload,morph">
"preload" and "morph" extensions are used in this part of the tree...
</body>
```
