Bootstrap 3's Collapsed Navigation Remains Open after Clicking Menu Links
In a typical Bootstrap 3 navigation setup, clicking on menu links in a collapsed menu should cause the menu to close automatically. However, some users have encountered an issue where the menu stays open after menu link selection.
Understanding the Problem
The issue arises because the default behavior of the Bootstrap collapse plugin is to toggle the element's visibility when its trigger button is clicked. This means that clicking within the collapsed menu itself, including on menu links, does not trigger the collapsing action.
Solution
To solve this problem, a JavaScript event listener can be added to the document. This listener detects when a user clicks within the collapsed navigation and automatically hides it. Here's an example code:
$(document).on('click','.navbar-collapse.in',function(e) {
if( $(e.target).is('a:not(".dropdown-toggle")') ) {
$(this).collapse('hide');
}
});
Explanation
- $(document).on binds an event listener to the document for clicks on elements matching the selector .navbar-collapse.in. This ensures the event is triggered only when the navigation is collapsed.
- The if condition checks whether the clicked element (e.target) is an anchor tag that is not a dropdown toggle (".dropdown-toggle"). Dropdown toggles are excluded to prevent collapsing the menu when their sub-menus are accessed.
- If the condition is met, the collapse('hide') method is called on the clicked element, which collapses the navigation.
This solution ensures that the collapsed menu closes automatically when users click on menu links, providing a seamless and user-friendly navigation experience.

Jul 26, 2025 am 07:04 AM
Different browsers have differences in CSS parsing, resulting in inconsistent display effects, mainly including the default style difference, box model calculation method, Flexbox and Grid layout support level, and inconsistent behavior of certain CSS attributes. 1.

It is recommended to use box-sizing:border-box in a unified manner; 3. Flexbox and Grid perform differently in edge cases or in old versions. More tests and use Autoprefixer; 4. Some CSS attribute behaviors are inconsistent. CanIuse must be consulted and downgraded.
