How can I implement keyboard navigation for a JavaScript drawer?

You can achieve keyboard navigation by adding event listeners for keydown events. Use the arrow keys to navigate through the items.

Can you provide a code example for that?

Sure! Here's a simple example:

const drawerItems = document.querySelectorAll('.drawer-item');
let currentIndex = 0;

function handleKeyDown(event) {
    if (event.key === 'ArrowDown') {
        currentIndex = (currentIndex + 1) % drawerItems.length;
    } else if (event.key === 'ArrowUp') {
        currentIndex = (currentIndex - 1 + drawerItems.length) % drawerItems.length;
    }
    drawerItems[currentIndex].focus();
}

document.addEventListener('keydown', handleKeyDown);

What if I want to close the drawer with the Escape key?

You can add another event listener for the Escape key to close the drawer. Here's how:

function handleKeyDown(event) {
    if (event.key === 'Escape') {
        closeDrawer(); // Your function to close the drawer
    }
    // existing code for ArrowDown and ArrowUp
}
