[IR-ext] selection support for complex ItemTemplate #611
Description
Anything else we need to know?
By design, IR-extensions only properly supports selection if the root element in the item-template is a SelectorItem derived class.
What would you like to be added:
Allow the target element of selection to be not just the template root.
This should probably be done through some marker property, ex:
<muxc:ItemsRepeater ItemsSource="ASD"
utu:ItemsRepeaterExtensions.SelectionMode="Single">
<muxc:ItemsRepeater.ItemTemplate>
<DataTemplate>
<Border>
<utu:Chip Content="{Binding}" utu:ItemsRepeaterExtensions.IsSelectionTarget="True" />
</Border>
</DataTemplate>
</muxc:ItemsRepeater.ItemTemplate>
</muxc:ItemsRepeater>or
<muxc:ItemsRepeater ItemsSource="ASD"
utu:ItemsRepeaterExtensions.SelectionMode="Single"
utu:ItemsRepeaterExtensions.SelectionTargetName="Selectable">
<muxc:ItemsRepeater.ItemTemplate>
<DataTemplate>
<Border>
<utu:Chip x:Name="Selectable" Content="{Binding}" />
</Border>
</DataTemplate>
</muxc:ItemsRepeater.ItemTemplate>
</muxc:ItemsRepeater>Why is this needed:
In figma, we often encounter case where it is impossible to generate a "clean/lean" item-template. And, we need to support these scenario, where the targeted SelectorItem can be found nested under the item-template.
