🎯 Goal
This PR aligns overriding functionality between the VirtualizedMessageList (VML) and the regular MessageList (ML).
The goal is to be able to integrate components like React Aria's GridList into ML.
Currently, VML supports overriding the list and item components via
additionalVirtuosoProps.components. This PR adds the same ability to ML via the ComponentContext.🛠 Implementation details
We add two more components to ComponentContext:
ul).li).These components are consumed in MessageList and in
renderMessages()respectively.This makes the following usage possible:
Sometimes it's also valuable to be able to access the current
RenderedMessageitem from MessageListItem component. In VML it's possible by accessing Virtuoso's context to getprocessedMessagesand using thedata-indexattribute to get item's index.To align this functionality with ML, this PR adds
processedMessagesto MessageListContext, and addsdata-indexattribute to message list items.🎨 UI Changes
None by default.
