nav-tabs Not Scrolling with overflow-x: scroll

Question

I tried to use nav-tabs from Bootstrap 4, and when it has too many items, I wanted to make it scrollable.

First, the default behavior is moving items to next line. I fixed this with white-space: nowrap and flex-wrap: nowrap.

And I realized that the container is expanding along x axis even there's an disabled scrollbar. I tried to fix it with giving max-width: 100%, but it's not working. I found that using specific px value makes it work, but it's not a good solution for me.

HTML:

<ul class="nav nav-tabs">
  <li class="nav-item px-1">
    <a class="nav-link active">Active Tab</a>
  </li>
  <li class="nav-item px-1">
    <a class="nav-link">Tab</a>
  </li>
  <li class="nav-item px-1">
    <a class="nav-link">Tab</a>
  </li>
</ul>

CSS:

.nav {
  white-space: nowrap;
  flex-wrap: nowrap;
  max-width: 100%;
  overflow-x: scroll;
  overflow-y: hidden;
  -webkit-overflow-scrolling: touch
}

.nav li {
  display: inline-block
}

Answer 1

Use display:block!important; to .nav instead display:flex

.nav {
  white-space: nowrap;
  display:block!important;
  flex-wrap: nowrap;
  max-width: 100%;
  overflow-x: scroll;
  overflow-y: hidden;
  -webkit-overflow-scrolling: touch
}

.nav li {
  display: inline-block
}
