Nested <ul> elements causing layout issues in Bootstrap 5 when using flexbox
I just started working with I'm working on a project and hit a roadblock. I'm stuck trying to I am currently working with an scenario with nested `<ul>` elements inside a Bootstrap 5 layout... I have a main navigation menu that uses flexbox, and for some of the menu items, I want to include submenus as nested `<ul>` elements. The question arises when I try to display these submenus; they appear misaligned and overflow outside the main navigation bar instead of being displayed properly underneath their parent. I've tried using the `position` property to control the submenu placement, but that leads to unexpected results where the submenu appears in the wrong position relative to its parent item. Here's a simplified version of my HTML structure: ```html <nav class="navbar navbar-expand-lg navbar-light bg-light"> <div class="container-fluid"> <ul class="navbar-nav me-auto mb-2 mb-lg-0"> <li class="nav-item"> <a class="nav-link" href="#">Home</a> </li> <li class="nav-item dropdown"> <a class="nav-link dropdown-toggle" href="#" role="button" data-bs-toggle="dropdown" aria-expanded="false"> Services </a> <ul class="dropdown-menu"> <li><a class="dropdown-item" href="#">Web Development</a></li> <li><a class="dropdown-item" href="#">SEO Services</a></li> <li class="dropdown-item dropdown-submenu"> <a href="#" class="dropdown-item dropdown-toggle">Design</a> <ul class="dropdown-menu"> <li><a class="dropdown-item" href="#">Graphic Design</a></li> <li><a class="dropdown-item" href="#">UI/UX Design</a></li> </ul> </li> </ul> </li> </ul> </div> </nav> ``` In my CSS, I have tried to adjust the submenu positioning like so: ```css .dropdown-submenu { position: relative; } .dropdown-submenu .dropdown-menu { position: absolute; left: 100%; top: 0; } ``` Despite these attempts, the submenu still doesn't display correctly and sometimes overlaps with other items in the navbar. I've also ensured that I included the necessary Bootstrap JavaScript and CSS files, but the scenario continues. Is there a specific way to handle nested `<ul>` elements within Bootstrap's flexbox layout, or do I need to modify my approach? Any guidance would be greatly appreciated! I'm working on a application that needs to handle this. Any help would be greatly appreciated! For context: I'm using Html on Ubuntu. Any help would be greatly appreciated! I'm using Html LTS in this project. Any ideas how to fix this? Has anyone else encountered this? I'm working on a desktop app that needs to handle this. I'd be grateful for any help. I'm on Ubuntu 20.04 using the latest version of Html. Am I missing something obvious?
