Stacks don't work on this... They work in the file artboard, but not in the preview or on the share link.
Please consider making stacks work for accordion menus because it's too time consuming to use auto-animate if you have a lot of sections in the accordion (also the point is for it to work on one single artboard).

Yes please! Trees, accordions, progressive disclosure forms, and the like would all come to life without us having to draw up (and wire together) every permutation of open and closed things!

I wish it could work with the stacks. It works when you are editing the file, but when you publish the prototype it doesn't.

I have the same problem, since the beginning of our project I have some expanding components and it is very important to move the content when the component expands - in design mode it is just perfect, but in preview mode, it isn't.

Yes, I would like the stack to update when a component inside it auto-animates to a larger or smaller state!

Absolutely crucial! please add this ASAP. It would help with my workflow immensely and save a ton of time.

+1 here as well. Works perfectly in the Design mode so it's a shame it doesn't in Prototype mode.

Constantly run into scenarios where this would be insanely helpful. +1

+1 Here! Missing this virtually every project I do, would be an amazing addition.

When I launch a preview of a page including a component whose shape changes (addition of an element in the component) it overflows despite the use of the stack function.

In the same way that stacks resizes it would be great if screens could resize their height dynamically. This would allow for auto-animating between different component states and the elements around them to move but retain the spacing.

An example would be in a form that works with progressive disclosure based on selecting different answers. Rather than animating between two screens, it could be between two states of a component and the screens responds dynamically.

When you have a lot of vertical content, duplicating artboards to create a dropdown menu requires a lot of effort, especially when each message has an accordion style dropdown menu. It would be nice to have the benefits of Stacks for this behavior.

Auto animate? the point of components is to make everything happen in one art board! please implement this feature, i though stacks will take care of it, until i tried !

Expanded/collapsed states are useless as long as preview mode does not adapt to them. A real shame and lost some hours due this particular design...

Since the stack dynamically expands (changes) in design mode, I have spent some time understanding that this does not happen in Preview.
I can understand why people might think this is annoying to have by default, but it could be an additional option when setting up a stack..

Anyways, it would really be incredibly useful to have this behaviour in the preview too.

I'd like this feature also, it feels like a natural fit for Stacks. What happens now is the opened state overlays the content beneath the closed state.

Elaine, this will not currently work (with auto-animate or otherwise) unless we put all the page's content into one giant component and manually position the content for each state. This precludes making a non-scripted flow.

FWIW, I hope I'm wrong, but I can't get this to work. Yes, I have the most recent version.

It is so sad that this feature is missing. I have a list with a lot of expanding elements. When changing the state to "expanded" everything adjusts just fine in design mode. Unfortunately it does not adjust in preview which forces me to add 2342346456 additional artboards to present every possible combination of expanded elements. This is really really annoying

I could really use this feature in prototype now. I have a sidebar with a ton of filters where I have expanded/collapsed states. Right now the expanded state in prototype just goes over the other elements.

The Problem: I have two components A & B. In A's default state component B is y px beneath A. Component A size expands or contracts by z px and changes to a new state. Currently, component B is now y + z px from the bottom of component A.

The Solution: Components that can change shape between states should "push or pull" other components by fixed padding defined assumed by the system or defined by the designer. This behavior should be able to be chained between multiple components & other objects.

Applications: Expandable lists, expandable cards, & my quality of life improves.

Savings: No need to create an endless number of artboards to express simple behavior between components or super long write-ups to hand off to a developer.

Current Time Cost: Per component, n, that has a number of states, y, on the artboard a designer has to create (n*y)! number of artboards to describe the screen behavior. This is a massive pain in the butt! It costs countless hours of write-ups and reconciliation with developers.

This wold be a really cool thing to implement. You already to auto-animate so creating a stack that animate should be relatively simple. Let's say you have a stack of expanding components. Then as each component expands, the stack responds and expands as well.
