Where do I find API documentation for $refs stuff?

[starleaf1]

Hello.

From this page https://vuetifyjs.com/en/components/date-pickers/ I found that VDatePicker has a .activePicker attribute which can be accessed via $refs['myDatePicker'], I also found that VMenu has $refs['myMenu'].save() method. Is there a documentation for these '$refs interfaces' on Vuetify?

I've also searched for this, but couldnt find it so far. Probably its best to look through the sources and "discover" them youself :)
