Question

I want to create two fixed scrollable left sidebars. How can i make both of them be scrollable independent of each other?

The following code isn't working.

.category {
  position: fixed;
  height: 250px;
  overflow-y: scroll;
  overflow-x: hidden;
  z-index: 1;
}
.sub-category {
  position: fixed;
  top: 250px;
  overflow-y: scroll;
  overflow-x: hidden;
  z-index: 1;
}

<div class="small-2 columns category">
  <ul>
    some list elements
  </ul>
</div>

<div class="small-2 columns sub-category">
  <ul>
    other list elements
  </ul>
</div>

Well, a few things you should note :

ul needs to have a li tag as a containing element.
If the two adjacent elements have fixed positioning, they would overlay, hence you need to position them accordingly. See the left propoerty I have added for a better understanding.

ul {
    margin: 0;
    padding: 10px;
}
ul li {
    list-style-type: none;
}
.category {
    background-color: #bbb;
    position: fixed;
    display:inline-block;
    height: 250px;
    overflow-y:scroll;
    overflow-x:hidden;
    z-index: 1;
}
.sub-category {
    background-color: #eee;
    position: fixed;
    display: inline-block;
    height: 250px;
    overflow-y:scroll;
    overflow-x:hidden;
    z-index:1;
    left: 200px;
}

<div class="small-2 columns category">
    <ul>
        <li>some list elements</li>
        <li>some list elements</li>
        <li>some list elements</li>
        <li>some list elements</li>
        <li>some list elements</li>
        <li>some list elements</li>
        <li>some list elements</li>
        <li>some list elements</li>
        <li>some list elements</li>
        <li>some list elements</li>
        <li>some list elements</li>
        <li>some list elements</li>
        <li>some list elements</li>
    </ul>
</div>
<div class="small-2 columns sub-category">
    <ul>
        <li>child list elements</li>
        <li>child list elements</li>
        <li>child list elements</li>
        <li>child list elements</li>
        <li>child list elements</li>
        <li>child list elements</li>
        <li>child list elements</li>
        <li>child list elements</li>
        <li>child list elements</li>
        <li>child list elements</li>
        <li>child list elements</li>
        <li>child list elements</li>
    </ul>
</div>
