Navbar links in Bootstrap unexpectedly expanding in width

My website has a navigation menu that looks like this:

https://i.stack.imgur.com/1R8mv.png

However, when I click on a menu item, the link container inherits the width of the dropdown menu. Is there a way to prevent this using purely CSS?

I am currently using Bootstrap 3.4 for my navigation.

The goal of my navigation is to have drop-down menus increase the height of the navigation div. However, by setting the dropdown menu to position:relative, the parent menu item ends up inheriting its width which is causing confusion. Any suggestions on how to solve this issue would be greatly appreciated!

If you need more information, feel free to ask. Here is a link to my jsFiddle: Here is a jsFiddle.

Below is the current code structure of my navigation:

<ul class="nav navbar-nav navbar-right">
        <li class="first expanded dropdown menu-4929 active"><a href="/" title="" data-target="#" class="dropdown-toggle menu-4929 active" data-toggle="dropdown">About Us</a>
            <ul class="dropdown-menu dropdown-menu-left">
                <li class="first leaf menu-4936 active"><a href="/" title="" class="menu-4936 active">The Museum</a></li>
                <li class="leaf menu-4937 active"><a href="/" title="" class="menu-4937 active">The Design</a></li>
                <li class="leaf menu-4938 active"><a href="/" title="" class="menu-4938 active">Our Team</a></li>
                <li class="last leaf menu-4939 active"><a href="/" title="" class="menu-4939 active">Work Opportunities</a></li>
            </ul>
        </li>
        <!-- More navigation code here -->
    </ul>

Answer №1

To enhance the layout, switch from using position: relative; to position: absolute; within the styling of the .dropdown-menu class

ul.dropdown-menu {
  position: absolute;
}

Answer №2

Consider adding a specified width to the parent <li> element. This will help in preventing it from incorporating the width of any child <ul>

Answer №3

.. updated response to address your query, check out this Plunker link for the solution. Make use of the suggested CSS code snippet below:

https://i.stack.imgur.com/hvzjk.gif

code

.dropdown-menu {
    position: relative;
z-index: 1000; 
}

.nav .open > a, .nav .open > a:hover, .nav .open > a:focus{width:120px;margin-left:0px;}

.test{width:115px;}

Hopefully, this code will resolve your issue.

Answer №4

If you're looking to incorporate JQUERY into your project, this method will give you the functionality you desire.

Check out this JSFiddle link to see it in action

$('.expanded').click(function(event) {
event.preventDefault();
$('.dropdown-menu-left').css('position', 'absolute');
console.log('position absolute');
setTimeout(function(){
console.log('menu clicked');
//Get the height of the UL nested and add the size of nav + the bottom margin
var navheight = $('.open .dropdown-menu-left').height() + 52 + 20;
console.log(navheight);

$('.navbar').height(navheight);
console.log('set height');

}, 0)
});

By the way, you'll need to customize the off-focus behavior according to your specific requirements.

Answer №5

To maintain the width of the toggling anchor element during dropdown events, follow these steps:

$(document).ready(function () {
  var anchorWidth = 0
  $('.dropdown').on('show.bs.dropdown', function (e) {
    // e.relatedTarget represents the anchor element that triggered the event
    anchorWidth = $(e.relatedTarget).width()
  })
  $('.dropdown').on('shown.bs.dropdown', function (e) {
    $(e.relatedTarget).width(anchorWidth)
  })
});

NOTE: This solution is specifically designed for Bootstrap v3.3.6 and later versions due to a known issue with the relatedTarget property in v3.3.5 and earlier.

Answer №6

Here are the necessary instructions.

Please inform me if I have overlooked any points you have made.

What alterations have I made? Check my inline comments below

ul.dropdown-menu {
  
  /* Position Relative: Always respects its parent */ 
  position: absolute;
  
  /* Auto Horizontal scrollbar will be displayed without this */
  overflow-x: auto;
  
  /* Prevents menu items from being cropped when overflow-x is set as hidden */ 
  width: auto;
  
  /* No changes made here*/
  height: auto;
  margin: 0;
  border: none;
  -webkit-border-radius: 0 !important;
  -moz-border-radius: 0 !important;
  -ms-border-radius: 0 !important;
  -o-border-radius: 0 !important;
  border-radius: 0 !important;
  -webkit-box-shadow: none;
  -moz-box-shadow: none;
  -ms-box-shadow: none;
  -o-box-shadow: none;
  box-shadow: none;
  
  /* Removes space above each drop down item*/
  padding-top:0;
}

Thank you

When an element is positioned absolutely within a relative container, it will automatically inherit its width from the relative container. This means that the absolute element's width will be set to 100% of the relative container's width. If you want to override this default Bootstrap behavior, you can change the position of the container to static and then give a relative position to the specific container whose width you want to be inherited for the dropdown menu.
