## What it is
Yamm3 is a lightweight, pure-CSS megamenu component for Bootstrap 3 that reuses the standard navbar markup and Bootstrap's fluid grid system. It supports fixed and responsive layouts and can embed almost any Bootstrap element inside dropdown menus.

## Use cases
- add a megamenu to a bootstrap 3 navbar
- create fullwidth dropdown navigation menus
- build responsive mega dropdown with grid columns
- put forms or accordions inside a bootstrap dropdown menu
- css-only megamenu without extra javascript

## When to choose
- your project is built on Bootstrap 3 and needs a megamenu
- you want a lightweight CSS-only solution using standard navbar markup
- you need fullwidth or grid-based dropdown menus

## When to avoid
- you use Bootstrap 4 or 5 - use the newer Yamm version instead
- you need a modern framework component like React or Angular menus
- you need active development or new features
