How to right align a CSS dropdown to its parent div? - html

Question

I want to create a dropdown that right aligns itself to its parent element
Something like this, but where the dropdown's right edge is aligned to its parent's right edge
This link contains the styling I want, the alignment is just not working properly. Any help would be very much appreciated!
a {
text-decoration: none;
}
nav {
font-family: monospace;
}
ul {
background: darkorange;
list-style: none;
margin: 0;
padding-left: 0;
}
li {
color: #fff;
background: darkorange;
display: block;
float: left;
padding: 1rem;
position: relative;
text-decoration: none;
transition-duration: 0.5s;
}
li a {
color: #fff;
}
li:hover {
background: red;
cursor: pointer;
}
ul li ul {
background: orange;
visibility: hidden;
opacity: 0;
min-width: 5rem;
position: absolute;
transition: all 0.5s ease;
margin-top: 1rem;
left: 0;
display: none;
}
ul li:hover>ul,
ul li ul:hover {
visibility: visible;
opacity: 1;
display: block;
}
ul li ul li {
clear: both;
width: 100%;
}

<li>Sub-2</li>
<li>Sub-3</li>

Convert left: 0 to right: 0 and change some CSS properties can right-align your dropdown

display: block;
float: left;
