Creating a multilevel dropdown menu using elements from Twitter Bootstrap 2 requires a custom implementation.
Original Response Pre-v2.1.1
Bootstrap 2 does not natively support multilevel dropdowns. To achieve this, you can use additional CSS to position submenu dropdowns adjacent to the parent menu item.
.dropdown-menu .sub-menu { left: 100%; position: absolute; top: 0; visibility: hidden; margin-top: -1px; } .dropdown-menu li:hover .sub-menu { visibility: visible; display: block; } .navbar .sub-menu:before { /* Styling for the arrow pointer */ border-bottom: 7px solid transparent; border-left: none; border-right: 7px solid rgba(0, 0, 0, 0.2); border-top: 7px solid transparent; left: -7px; top: 10px; } .navbar .sub-menu:after { /* Additional styling for the arrow pointer */ border-top: 6px solid transparent; border-left: none; border-right: 6px solid #fff; border-bottom: 6px solid transparent; left: 10px; top: 11px; left: -6px; }
Updated Response v2.1.1 and Later
For Bootstrap versions 2.1.1 and above, multilevel dropdowns are included by default. Simply follow the guidelines in the documentation:

There are three ways to selectively include CSS on a specific page: 1. Inline CSS, suitable for pages that are not frequently accessed or require unique styles; 2. Load external CSS files using JavaScript conditions, suitable for situations where flexibility is required; 3. Containment on the server side, suitable for scenarios using server-side languages. This approach can optimize website performance and maintainability, but requires balance of modularity and performance.

CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.
