[WIP] This is an initial and in-progress implementation of Modal and Backdrop animation support. These changes were cherry-picked (file-level) from branch gmurcia/tearsheet, originating from the following commits: - c027e56 chore: Initial modal/backdrop animation impl - 1927470 chore: Animation tweaks. - a7f4102 chore: Implement TearsheetGroup for unbounded tearsheet levels Commit-generated-by: Claude Opus 4.6 <noreply@anthropic.com> Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
…AnimationsProvider + hooks Replace custom `animated` prop with `hasAnimations` across Modal, ModalContent, ModalBox, and Backdrop. Wire up `useHasAnimations` hook in ModalContent and Backdrop so both participate in AnimationsProvider context. Add second example demonstrating the AnimationsProvider path.

In `@packages/react-core/src/components/Modal/examples/ModalAnimated.tsx`:
- Around line 16-40: ModalAnimated’s Modal configuration is missing an onClose
handler, preventing Escape-key and header close-button dismissal. Add
onClose={handleModalToggle} to the Modal component in the ModalAnimated example
while preserving the existing footer button handlers.
In `@packages/react-core/src/components/Modal/examples/ModalAnimatedProvider.tsx`:
- Around line 25-53: Add onClose={handleModalToggle} to the Modal component in
the ModalAnimatedProvider example so the header close button and Escape key both
dismiss the modal consistently with the existing button handlers.
In `@packages/react-core/src/components/Modal/ModalContent.tsx`:
- Around line 77-84: Animated modal content remains mounted after closing
because ModalContent only skips rendering when animations are disabled. Add
close-animation completion handling around useHasAnimations and the isOpen state
so the component unmounts after the exit transition finishes, using a
transition-end callback or timeout fallback, while preserving immediate null
rendering for non-animated closes.
In
`@packages/react-styles/src/css/components/ModalAnimations/modal-animations.css`:
- Around line 14-22: Update the transition declaration in
.pf-v6-c-modal-animated-open to include opacity alongside transform and
visibility, preserving the existing timing and easing so opening the modal fades
it in as well as moving it.

In addition to the file comment below, can you move the styles that you added to the react-styles directory to the Modal > examples directory? There's an issue where those styles arent being applied, and due to the update to ModalContent's return null check, it's always rendering the Modal as visible and unable to close it.
What I did locally was create a Modal.css file in Modal > examples, copy+pasted the contents of backdrop-animations.css and modal-animations.css from react-styles into it, then add a import './Modal.css'; line in the Modal.md file. This should show the animations correctly for the preview deployment.

patternfly/patternfly-design#1443 might be relevant to reference here |
|
Hey @thatblindgeye I cant tell, are these using any of the pf motion tokens? |
|
@kaylachumley I dont believe so, this PR is defining some custom transition/animation values, some based on Carbon/with a Carbon equivalent |
|
@mcoker @jcmill @andrew-ronaldson @lboehling pinging you as well just to get yall tagged in the PR, since we had only discussed this yesterday during dev/design sync. |
|
I’d like to drop the backdrop animation and focus on the modal itself. duration: --pf-t--global--motion--duration--fade--default timing: --pf-t--global--motion--timing-function--decelerate transform: translate3d(0, -24px, 0). For other animated components we typically exit immediately or much faster than how it entered. I'm looking into a token for that now. Should we close this and make a core issue to get these in @thatblindgeye |
|
@andrew-ronaldson I think this PR can stay open for the React updates we'll need (mainly new props); we can have this PR updated to remove any styles that live inside it and bump the core version once updates are made there. I have this core issue open for the animation styles we'll want to live inside PatternFly patternfly/patternfly#8517 Coker got assigned it during yesterday's sprint planning. Would you mind leaving a comment on the above core issue with the necessary styles/tokens we'll want? Or if the design ticket is closed out and has info just linking that in the core issue |
|
@thatblindgeye core PR is up - patternfly/patternfly#8584. The changes I needed to make to this branch to get it to work are in GAUNSD#1 |
|
Just a note, as part of this PR we should potentially include some verbiage about using the isOpen prop in favor of conditionally rendering the Modal, as at the very least that might interfere with exit animations (and there could be other, non-animation caveats) |

Agreed on updating the content. Any thoughts @thatblindgeye @mcoker @wise-king-sullyman @nicolethoen on how to structure the content in Modal.md? With a change as strong as having animations on by default it'd be best to highlight this code snippet of how consumers render if (!isOpen) {
return null;
}

Styles all look good to me. Just need to remove the animation stylesheets from this branch.

I'll drop the same comment as I left in GAUNSD#1. I wonder if that should be a follow up.

Video: Slowed down animations to 25% speed

Detail:
ModalBox'sreturn nullNotably; the ModalBox was previously returning null which made the animation less desirable since the entire modal content was not rendered.
Now the ModalBox will skip this and only
return nullwhen animations are not set.Detail:

Ideally these styles would live upstream in patternfly/modal-box.scss and other relevant areas.

\instead of the/.While running locally, some build scripts fail because of this and tweaks were made in order to get a successful build.
