<!--
we would need a container like this for sticky dates to work well,
but that could be somewhat tricky to make work in Brawl:
- the list view would have to support a hierarchy rather than a flat list. Is there anything else we could use this for?
- this might be doable, just mapping the child instance index back from a dom event like in _onClick would need to index set as a data attribute perhaps?
- we'd have to fabricate an entry in the TilesCollection out of thin air (e.g. not an event) to render the date separator in the container? Or perhaps that could be logic of the container creation code?
so a tile entry could have a group property, and if the group property is not yet known or different than the previous/next tile or something, we create a new one, with a function that maps the group info to a View (which would render the container and the date separator). The view would also need to provide a way to add tile nodes at a given index, see insertAt in onAdd there.
e.g a GroupListView, and if onAdd, a given property on the item is different from both the previous and next item, create a new group view. Could pass a group function, item => item.date
another group could be a continuation entry, so we can have the avatar only show once and stay sticky for a group of messages,
this could work with a group function like item => item.sender, where this only looks at the immediate siblings of an item to see if they belong to the same group.
so nested groups could make sense indeed
it would be good if the nesting could all be handled at the top level in case of multiple levels
also, to have the sticky avatars, they would need to be a sibling of event tiles, because they need to stick to their parent,
the sender container. So the DOM would be different, which is annoying but sort of ok, if we can make the code not too different for
other layouts we might want.
