@inherits DComponentBase

@* daisyUI FAB: https://daisyui.com/components/fab/ . Opening is daisyUI's own :focus-within rule (there is no
   open-state class): the trigger is the focusable first child, and focus moving out of the FAB closes it. The order
   of the children matters to daisyUI: trigger, then Close or MainAction, then the speed-dial items (ChildContent,
   e.g. DButton Size="DSize.Lg" Shape="DButtonShape.Circle", optionally inside a <div> with a text label). *@
