How do you load a lot of items in ExposedDropdownMenu UI freezes for me if there are to many items.

[Jessica Ernst]

how many items? my biggest exposed that I have, has 31 items and no Problem like that

[K Merle]

Around 300 😄

[K Merle]

It's more like auto-complete TextField

[Jessica Ernst]

wow that doesn’t sound like a good idea, not just for freezing screen but which user wants to scroll through 300 items in a exposed dropdown?

[Jessica Ernst]

I wouldn’t want it to be honest

[K Merle]

That's true.

[K Merle]

I am still not sure if I should have UI issues, or I'm doing something wrong.

[Jessica Ernst]

I think yes that there comes ui issues I think is no surprise. I don’t think that an exposed dropdown should hold so many items without trouble in UI. When you open a dropdown the composition starts I think that will block the mainThread to long that’s why everything is freezing. I don’t know your special case for doing that, but I would think which opportunities maybe better for this case

counter-argument: I don't think that developers should have to think about sampling dropdown items. It's difficult to come up with a number that'll be smooth on all devices. @K Merle wanna file a feature request for ExposedDropdownMenu to use a lazy list?
