Bootstrap Collapsed menu opening then immediately collapsing again
Uhg, it turns out I had a major brain fart! I was using a bootstrap 2.x CSS file, along with a bootstrap 3.x js file.
An in
class is added when a click is triggered to open the menu but the collapse
class isn't removed.
Adding this css for overriding collapse
properties worked for me:
.navbar-collapse.in {
display: block !important;
}
You have Version Mismatch in bootstrap.css and bootstrap.js file/cdn. check once and you will realize the cause.
