Accessing the internal state

To access the internal state of the Menu, use a function as a children (commonly known as a render prop). You'll get access to the internal state isOpen and method onClose.

1<Menu>
2  {({ isOpen }) => (
3    <React.Fragment>
4      <MenuButton>{isOpen ? "Close" : "Open"}</MenuButton>
5      <MenuList>
6        <MenuItem>Download</MenuItem>
7        <MenuItem onClick={() => alert("Kagebunshin")}>Create a Copy</MenuItem>
8      </MenuList>
9    </React.Fragment>
10  )}
11</Menu>

Letter Navigation

When focus is on the MenuButton or within the MenuList and you type a letter key, a search begins. Focus will move to the first MenuItem that starts with the letter you typed.

Open the menu, try and type any letter, say "S" to see the focus movement.

1<Menu>
2  <MenuButton
3    px={4}
4    py={2}
5    transition="all 0.2s"
6    borderRadius="md"
7    borderWidth="1px"
8    _hover={{ bg: "gray.100" }}
9    _expanded={{ bg: "red.200" }}
10    _focus={{ outline: 0, boxShadow: "outline" }}
11  >
12    File <ChevronDownIcon />
13  </MenuButton>
14  <MenuList>
15    <MenuItem>New File</MenuItem>
16    <MenuItem>New Window</MenuItem>
17    <MenuDivider />
18    <MenuItem>Open...</MenuItem>
19    <MenuItem>Save File</MenuItem>
