How can I disable `HorizontalPager` scroll (via `userScrollEnabled`) when the user started a `LazyColumn` scroll (and vice versa)? Do I need to write a complex `NestedScrollConnection`?

Are you using the accompanist `HorizontalPager`?

For a consistent user experience, I would disable horizontal scrolling altogether. Having two directions of scrolls in the same page is not a good ux

Material design guidelines don't say so (<https://material.io/components/tabs#behavior|https:/material.io/components/tabs#behavior>), and many users already asked for this feature.

Many apps (made with the traditional Android `View`s) have the desired behavior - and I could achieve it as well using my own `Pager`...

Of course, the UX I showed is terrible.

```val listState = rememberLazyListState()```
<https://developer.android.com/reference/kotlin/androidx/compose/foundation/lazy/LazyListState#isScrollInProgress()>

This should tell you whether someone is scrolling around vertically, you can simple change the value for `userScrollEnabled` based on it

<@U0135TSKN0K> I did that already but it's not enough. The very first drag will still dispatch X changes to the `HorizontalPager` and Y changes to the `LazyColumn`

I think it's due to how `HorizontalPager` detect drags: it uses `scrollable` instead of `draggable` (my `Pager` that doesn't have this problem uses `detectHorizontalDragGestures`)

PS: I can't really use my `Pager` because it's not lazy. I started re-implementing it using a `LazyLayout` yesterday

Might be worth writing a bug report or a feature request for accompanist itself

I implemented my own pager and got an acceptable result:

you should share your snippet so people can use it in the future
