Mega Menu Generator
Build a mega menu from a simple text outline: top-level items with columns of links, plus plain top-level links. The generator uses the accessible disclosure pattern – real buttons with aria-expanded and aria-controls – so keyboard, screen reader and touch users can open panels. The small JavaScript closes panels with Escape, on outside click and when focus leaves the menu, and can optionally open panels on hover for mouse users.

Mega Menu Generator FAQ
Why not role="menu"?
ARIA menus are for application menus with arrow-key navigation. Website navigation with links is better as a list of links with disclosure buttons.
Does it work without JavaScript?
The panels stay closed, so make sure top-level pages are also reachable through links.
Is it mobile friendly?
Panels become part of the page flow on small screens, and buttons work with touch.
Big menus, simple code
Mega menus help when a site has many sections, but each panel should stay scannable: few columns, short labels and clear headings.
How it works: you fill in plain text fields and lists, and the generator writes clean, indented HTML and CSS in your browser. Everything you type is escaped before it is placed in the markup, links are checked so that javascript: and data: URLs cannot slip in, and the preview runs in a sandboxed frame without scripts. Nothing is uploaded or stored.
The code has no framework or build step: copy the HTML into a page, template or page-builder HTML block, and the CSS into your stylesheet. Class names use a prefix you choose (BEM style), so they do not clash with your theme, and colours come from your accent colour with automatic contrast checks.
Accessibility is built in: semantic landmarks and headings, real labels on form fields, visible focus outlines, enough colour contrast and layouts that reflow on small screens without horizontal scrolling. The notes under the output explain the decisions and what you still need to do on your side.
Use the presets to start from a typical example, then adapt the text. Related generators on this site cover the other parts of a website – navigation, footer, buttons, cards, forms, FAQ and call-to-action sections – so you can assemble a complete page from consistent pieces.
