Dropdown-toggle should be a link as well

Question

I have set up a dropdown toggle with BS4. The dropdown slides down nicely on hover. But now the product owner wants to have the toggle button as a clickable link (in my sample: href="https://www.yahoo.com). But I don't know how to achieve this. Is there a solution for this? Or is it easier to re-build the toggle menu to something else, to have a link seperated from a sliding div (or whatever) afterwards?

Here is my toggle, what I have so far:

html {
  font-family: Arial;
  font-size: 1.4rem;
  line-height: 1.4rem;
}

.dropdown {
  display: inline-block;
  padding: 0 7px;
}
.dropdown.show {
  background-color: rgba(255, 255, 255, 0.9);
}
.dropdown a::before {
  content: "";
}
.dropdown a.dropdown-toggle {
  cursor: pointer;
  padding: 3px 7px;
}
.dropdown a.dropdown-toggle::after {
  font-size: 1.4rem;
  content: ">";
  color: Orange;
  line-height: 1.4rem;
  border-top: 0;
  border-right: 0;
  border-bottom: 0;
  border-left: 0;
  vertical-align: top;
  transition: 0.5s;
}
.dropdown a.dropdown-toggle:active {
  pointer-events: none;
}
.dropdown a.dropdown-toggle:hover:after {
  transform: rotate(90deg);
}
.dropdown .dropdown-menu {
  min-width: initial;
  padding: 0.5rem;
  margin: 0;
  margin-left: 7px;
  font-size: initial;
  border-radius: 0;
  transition: all 0.5s;
  overflow: hidden;
  transform-origin: top center;
  transform: scale(1, 0);
  display: block;
  border: none;
  box-shadow: 0px 3px 6px rgba(0, 0, 0, 0.16);
}
.dropdown .dropdown-menu a.dropdown-item {
  font-size: 1.4rem;
  line-height: 1.6rem;
  text-decoration: none;
}
.dropdown .dropdown-menu a.dropdown-item:hover {
  color: Orange;
}
.dropdown:hover .dropdown-toggle {
  background-color: rgba(255, 255, 255, 0.9);
}
.dropdown:hover .dropdown-menu {
  transform: scale(1);
}

.dropdown-menu:hover + a:after {
  transform: rotate(90deg);
}

Update

The use of bootstrap's attribute and class was blocking this. i.e, data-toggle="dropdown" and .dropdown-toggle since they're tied to the framework.

In addition to pointer-events: none.

html {
  font-family: Arial;
  font-size: 1.4rem;
  line-height: 1.4rem;
}

.dropdown {
  display: inline-block;
  padding: 0 7px;
}
.dropdown.show {
  background-color: rgba(255, 255, 255, 0.9);
}
.dropdown a::before {
  content: "";
}
.dropdown a.cc-dropdown-toggle {
  cursor: pointer;
  padding: 3px 7px;
  text-decoration: none;
 
}
.dropdown a.cc-dropdown-toggle::after {
  font-size: 1.4rem;
  content: ">";
  color: Orange;
  line-height: 1.4rem;
  border-top: 0;
  border-right: 0;
  border-bottom: 0;
  border-left: 0;
  vertical-align: top;
  transition: 0.5s;
  display:inline-block;
}
.dropdown a.cc-dropdown-toggle:hover:after {
  transform: rotate(90deg);
}
.dropdown .dropdown-menu {
  min-width: initial;
  padding: 0.5rem;
  margin: 0;
  margin-left: 7px;
  font-size: initial;
  border-radius: 0;
  transition: all 0.5s;
  overflow: hidden;
  transform-origin: top center;
  transform: scale(1, 0);
  display: block;
  border: none;
  box-shadow: 0px 3px 6px rgba(0, 0, 0, 0.16);
}
.dropdown .dropdown-menu a.dropdown-item {
  font-size: 1.4rem;
  line-height: 1.6rem;
  text-decoration: none;
}
.dropdown .dropdown-menu a.dropdown-item:hover {
  color: Orange;
}
.dropdown:hover .cc-dropdown-toggle {
  background-color: rgba(255, 255, 255, 0.9);
}
.dropdown:hover .dropdown-menu {
  transform: scale(1);
}

.dropdown-menu:hover + a:after {
  transform: rotate(90deg);
}
