Morphing drawer menu

A menu button that morphs into a close icon while a drawer slides in.

Three bars become an X while a drawer slides over the page. Open, the drawer keeps the keyboard focus inside, Escape closes it and focus goes back to the button. The page behind is made inert.

Try it

<nav-drawer-morph>

Build one with your agent

Paste this into your agent. It asks you before it signs in, pays or goes further than checking and publishing.

Build me a Taggor component like "Morphing drawer menu" (nav-drawer-morph): A menu button that morphs into a close icon while a drawer slides in. Fetch https://taggor.dev/agent-setup/prompt.md and follow its instructions to set me up for Taggor. Ask me before you sign in, create an account, accept terms, pay for anything or type a secret. Check it with `taggor check` and publish it with `taggor publish`, and stop there. Do not promote it to production, attach it to a site, roll back anything or use --yes, --force or --force-drop-invalid unless I ask for exactly that in this conversation.
