Attributes to ignore during morphing

The htmx.config.morphIgnore option is an array of attribute names to ignore when morphing DOM elements.

Default: ["data-htmx-powered"]

Example


htmx.config.morphIgnore = ["data-htmx-powered", "data-analytics"];


<meta name="htmx-config" content='{"morphIgnore":["data-htmx-powered","data-analytics"]}'>

These attributes will be skipped during morph and settle operations.

If you use a strict style-src CSP, add "style" to this list to prevent CSP violations from inline style attribute copying. See Security Best Practices for details.
