Not possible to subclass

[airblade]

The controller adds some actions itself to avoid the user having to add them in their markup.

However these have the name of the controller hardcoded. For example:

stimulus-datepicker/src/datepicker.js

Line 92 in 0c4defd

let action = 'click->datepicker#toggle'

This means a child controller won't work properly.

Probably makes sense to add the action via an EventListener rather than markup?

[airblade]

Yes, I agree.

I quite liked just being able to set an attribute to add an event listener ;)

[Yasser]

Still could, just use click->${this.identifier}#toggle
