[Feature] Able to toggle sticky group headers in CollectionView

[velocitysystems]

Summary

We are using a grouped CollectionView and would like to disable sticky group headers.
A similar idea was previously discussed in the CollectionView spec.

API Changes

Add a new property UseStickyGroupHeaders (or similar) to CollectionView.
Default value should be false.

public static readonly BindableProperty UseStickyGroupHeadersProperty;
public bool UseStickyGroupHeaders { get; set; }

Intended Use Case

Currently, the default platform behaviour occurs which results in an inconsistent experience between the platforms. For example, by default group headers are sticky on UWP but not on iOS and Android.

According to issue 3172, CollectionView should have a property named IsHeaderSticky. However, I can't find it - @cabal95 also stated that in issue 3172.

Is this feature still planned for CollectionView?

Bump - I'd like the option to have sticky group headers on android / iOS

Created a proof of concept implementation here: https://github.com/xamcat/Scratch/tree/master/FormsStickyHeaders

Feel free to extend it directly into forms!

Thanks for this suggestion! As Xamarin.Forms is now in maintenance mode, this will not happen anymore for Xamarin.Forms. We're only adding bugfixes and stability fixes.

There is already a feature request open for this on .NET MAUI, make sure to upvote it there. Thanks!
