Bootstrap 侧边栏折叠菜单：之后

Question

I made a collapse menu with Bootstrap, works fine, but I can't make it so the link has the same color as the button:

.collapse-link a:after {
  font-family: 'Glyphicons Halflings';
  content: "\e114";
  color: $white;
  background-color: black;
}

.collapse-link a.collapsed:after {
  content: "\e080";
  background-color: white;
}

I would like the class="collapse-link" get the same background color as right now in the buttons in the right, so the full div will be following the buttons color when is collapse and when is not, right now just the buttons getting background color i would like the titles: test3 and test get the background color of the buttons beside.

Add following css to make it work:
