I used a timeline layout example in the JSFiddle where I added filter buttons. However, when I click on the TEST or GROEP button, the middle line gets cut off. Can anyone assist with this issue?
Refer to:

.timeline:before {
top: 0;
bottom: 0;
position: absolute;
content:" ";
width: 2px;
background: #ffffff;
left: 50%;
margin-left: -1.5px;
}
