ShadowRoot: clonable property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since April 2024.
The clonable read-only property of the ShadowRoot interface returns true if the shadow root is clonable, and false otherwise.
When the value is true, a shadow host cloned with Node.cloneNode() or Document.importNode() will include a copy of the shadow root.
By default the value is false.
It can be set to true using the clonable option of the Element.attachShadow() method or by setting the shadowrootclonable attribute of the <template> element that is being used to declaratively attach a shadow root.
Value
true if the shadow root is clonable, and false otherwise.
Examples
js
const host = document.createElement("div");
const shadowRoot = host.attachShadow({
mode: "open",
clonable: true,
});
shadowRoot.clonable;
// true
