When collapse is opened by default animation starts from 0 if content is changed about react-collapse HOT 8 CLOSED

I'm also met this bug several days ago. I'm looking forward for the moment when this bug will be fixed, and I can use this lib.

Hi @GeraldIstar! If you can debug it a bit and find the fix - that would be awesome. I would really appreciate any help!

Looks like problem is near to defaultStyle of Motion component
Here, in most cases compoent start from 0, but some times height provided from state is also equal to 0 (not sure, might be my fault).
https://github.com/nkbt/react-collapse/blob/master/src/Collapse.js#L151
This cause that 0-height is provided to newStyle here:
https://github.com/nkbt/react-collapse/blob/master/src/Collapse.js#L169
But I've just spent few time, and can suggest that I missed somthing.

Any news on this? I'm experiencing the same :(

from react-collapse.

The Motion component needs to have the same height set in defaultStyle as in the previously rendered static div. It's quite tricky to solve as at the moment there is no way to tell if the previous render call was a static one or not. Storing the static height between calls could be a solution but seems quite hacky to me. Any ideas?

@davidspiess I actually store current height between calls, so it is as hacky as hell already ;)

This does not seem like a hugely complicated issue (comparing to the flexbox one, for example). There is a PR, I'll check it asap.
