== Multi select for filtered lists ==
In the standard UI, multi selection targets the original unfiltered lists. However, those lists are often presented in several filtered lists in many cases. See content filtering in [[XAML_Changes_in_UBIK_WinX_3.5#Filtering_by_expressions|UWP]] and in [[Xamarin_XAML#Content_filtering|XamarinMobile]].
The multi select related XAML code (essentially <code>ListViewModel.BulkOperation</code>) in the standard UI can not be used directly in such scenarios. Because all filtered lists share the same original source list (<code>ListViewModel</code>). If the multi select feature is turned on from the original source list, all filtered lists will be affected.
