✅ Solutions

Very easy: we fully leverage the <Presence> component’s features to control the switching of child components.
but we need tag <Presence> as force-mount to keep it alive, becasue we focus in its child components, don’t want it to be destroyed immediately when closing.

In addition, we use force-mount in <Presence>, so, SelectContentProps's forceMount prop was no longer works. Should we consider removing it?

Why is no one updating this PR?

Could anyone please work on it?

[Hwacc]

I’ve resolved the merge conflicts in v2.7.0 and looking forward to review. It looks like quite a few people have run into issues with this Select component. @kricsleo , do we have plans to merge this PR into the next release? Thanks.

[kricsleo]

Sorry for the late response. I normally don't merge PRs 🙏, so I'll leave it to the author, zernonia.

I think @kricsleo meant to tag @zernonia and not just link to him here. (Also I'm doing it to highlight the fix as well).
