hx-preserve
The hx-preserve
attribute allows you to keep an element unchanged during HTML replacement.
Elements with hx-preserve
set are preserved by id
when htmx updates any ancestor element.
You must set an unchanging id
on elements for hx-preserve
to work.
The response requires an element with the same id
, but its type and other attributes are ignored.
Note that some elements cannot unfortunately be preserved properly, such as <input type="text">
(focus and caret position are lost), iframes or certain types of videos. To tackle some of these cases we recommend the morphdom extension, which does a more elaborate DOM
reconciliation.
