• https://learn.microsoft.com/en-us/fluent-ui/web-components/components/combobox
• https://primer.style/css/components/dropdown#alignment
• https://primer.style/view-components/components/alpha/actionmenu
• https://primer.style/react/ActionMenu

Notes:

• Differentiate between a "dropdown" and an "action menu"
• Allow nesting for complex menus
• Allow opening via right click instead of left click via a property
• Allow launcher via a slot and not requiring JavaScript.
