Q:

hide border-top in center of div

Here is what I am trying to achieve 

This is in my div's open state so normally you do not see any filters but instead just a full circle. What I am having trouble with is I dont know how to prevent a border on a small section.
Here is what I have below as well as a Codepen

.bold {
  font-weight: bold;
}

.bp-purple {
  color: #9696ff;
}

.bp-nyan {
  color: #67cfd6;
}

.bp-pink {
  color: #e49092;
}

.bp-green {
  color: #96cf6b;
}

.filter-options {
  text-align: center;
  margin: 15px 0 0 0;
}
.filter-options__intro {
  text-transform: uppercase;
  display: inline-block;
  border: 1px solid #222;
  border-radius: 50%;
  height: 80px;
  width: 80px;
  padding: 30px 0;
  color: #222;
}
.filter-options__intro i {
  margin: -5px 0 0 0;
  display: block;
}
.filter-options__intro:hover {
  color: #f93;
}
.filter-options__selections {
  border: 1px solid #222;
  position: relative;
  bottom: 30px;
  background: #FFF;
  text-align: left;
  padding: 15px;
  margin: 0 0 -25px 0;
}
.filter-options__selections .list-inline, .filter-options__selections .checkbox {
  font-weight: bold;
  text-transform: uppercase;
}
.filter-options__selections input {
  margin: 0;
}
.filter-options__selections .first {
  font-size: 1.2em;
}
.filter-options__selections .dotted-line {
  margin: 0 0 10px 0;
}

Edit 
Added sass tag as my codepen is in sass but not sure if stack lets me use it in snippets

A:

First you need to make <a> position relatively.
.filter-options__intro {
 position: relative;
}

Then add an css after selector, to cover up the black line
a.filter-options__intro:after {
    content: '';
    display: block;
    background: white;
    z-index: 1111;
    position: absolute;
    width: 75px;
    height: 1px;
    bottom: 0px;
    left: 0;
    right: 0;
    margin: auto;
    top: 20px;
}

Working example:
Overlap element using CSS :after
