Hi All, Is it possible to add a header item into a LazyColumnFor. So it appears once at the top of the List , but also scrolls with the list.

[Yann Badoual]

Just use a LazyColumn and iterate on your list manually

[Yann Badoual]

Wrap each item in a key bloc too

[Neil]

Ah ok, I think I see. Not sure what you mean by key bloc?

[Yann Badoual]

key(item){ }

[Yann Badoual]

From what I understand it's used when chaining the same composable in a loop, LazyColumnFor is using it

[Neil]

ok I’ll take a look at it some more , thanks for the quick reply 👍

I'd recommend checking out the Lazy DSL for this: https://cs.android.com/androidx/platform/frameworks/support/+/androidx-master-dev:compose/foundation/foundation/samples/src/main/java/androidx/compose/foundation/samples/LazyDslSamples.kt

[Neil]

Nice! thanks for pointing me to these samples. That looks to be the kinda thing I want to do. 😀

[Daniele B]

and what about a header which stays fixed and doesn’t scroll?
