Underline hover animation navigation bar

Hello there! 

I know that there is some post about this, and I found a good code for it . However, I cannot find a way to "stop the line" under the drop down menu links and make it 100% of the word, not beyond. How can I do? I post the picture of it below. Thank you in advance!

Here is the css code : 

.header-nav-item > a:after, .header-nav-folder-item > a:after {
  content:'';
  width: 0px;
  height: 1px;
  background: #fff;
  display: block;
  transition: width .2s ease;
}

.header-nav-item > a, .header-nav-folder-item:hover {
  background: none !important;
}

.header-nav-item--active > a:after, .header-nav-item:hover > a:after, .header-nav-folder-item:hover > a:after {
  width: 100%;
}

.header-nav-folder-item:hover > a {
  color: #fff !important;
}

Do you mean something like this?

I try the following code and it seems fine

.header-nav-folder-item > a {
  display: inline-block;
}

Let me know how it works on your site
