Hello,

Do you have plans to add the expand/collapse capability (and thus nested content) for List Items that the Material Design spec outlines?

This would be a huge benefit. Material UI has this capability - they call it "nested list items":

This capability could help fill the void that other control suites provide with controls like accordions, or "panel boxes" (a la Kendo UI). I realize that the Material Design spec does not currently show "accordions" or "panel boxes", but the nested list feature is shown by the spec.

Thanks and best wishes.
