Proto.Menu is a simple and lightweight prototype-based solution for context menu functionality on your page. * Lightweight: ~2 KB (~1.5 KB minified) * Unobtrusive: Plays nice with JS turned off, uses its own namespace * Cross-browser: Full A-Graded browsers support (Opera is supported through Ctrl + Left Click) * Fully customizable: Menu styling can (and is intended to) be easily defined in external stylesheet * Fast: Menu container is rendered on page load, and only changes position on click
