which files are necessary for bootstrap dropdown to work? - vue.js

Question

I am avoiding including the entire bootstrap source code in my app. All I need at this point is the bootstrap dropdown classes. I am trying to make a simple dropdown that looks like this...
<div class="dropdown">
<a data-toggle="dropdown" class="dropdown-toggle">display dropdown</a>
<ul
class="dropdown-menu dropdown-menu-right dropdown-menu-arrow dropdown-scrollable dropdown-content"
>
<li class="dropdown-item">Option 1</li>
<li class="dropdown-item">Option 2</li>
</ul>
</div>
I copied dropdown.scss from the tabler.io library.
This is all it contains...
.dropdown {
display: inline-block;
color: orange;
}
.dropdown-menu {
box-shadow: $dropdown-box-shadow;
min-width: 12rem;
}
.dropdown-item {
color: $text-muted-dark;
z-index: 1000;
}
.dropdown-menu-arrow {
&:before {
position: absolute;
top: -6px;
left: 12px;
display: inline-block;
border-right: 5px solid transparent;
border-bottom: 5px solid $border-color;
border-left: 5px solid transparent;
border-bottom-color: rgba(0, 0, 0, 0.2);
content: "";
}
&:after {
position: absolute;
top: -5px;
left: 12px;
display: inline-block;
border-right: 5px solid transparent;
border-bottom: 5px solid #fff;
border-left: 5px solid transparent;
content: "";
}
&.dropdown-menu-right {
&:before,
&:after {
left: auto;
right: 12px;
}
}
}
.dropdown-toggle {
user-select: none;
cursor: pointer;
&:after {
vertical-align: 0.155em;
}
&:empty:after {
margin-left: 0;
}
}
.dropdown-icon {
color: $text-muted;
margin-right: 0.5rem;
margin-left: -0.5rem;
width: 1em;
display: inline-block;
text-align: center;
vertical-align: -1px;
}
I know that my code is referencing this stylesheet because the font color is orange and the stylesheet's first rule includes color: orange.
I also know that my code detects the user clicking on the text because I tested by adding #click.prevent="doSomething()" where doSomething() simply console logged a message.The message did indeed print out in the Chrome dev tools console.
However, when I click on the words display dropdown, the dropdown menu does not open.
I understand there are javascript files I may need. Which files are those and how can I make sure my code uses this file? This is a Vuejs app using Nuxt.
