Simple Command Dialog for React

The Open Command Menu button sets an open state to true, and CommandDialog takes that state with its change handler, so Escape or a click outside sets it back. The dialog has a visually hidden title and description. The Command goes straight inside CommandDialog.

One CommandGroup with the heading Suggestions holds three CommandItems: Calendar, Search Emoji and Calculator. Each item's text is its only content.

Use a Command to run an action or jump somewhere. Use a Combobox when the choice is a value that stays in a form field.

CommandEmpty in the list says "No results found." It shows only when the search leaves nothing.

These items don't run anything yet. Pass onSelect to each CommandItem. Close the dialog in the same handler.

The arrow keys move through the items, Enter runs the highlighted one, and typing filters the list. Escape closes CommandDialog, and focus goes back to the button. CommandInput shows "Type a command or search..." until someone types. Command filters and ranks the items by their text on its own.
