Question

I have some list of vendors in my site, those vendors list are created manually.

Live Site

Those links are displaying in one single column div

Answer 1

you can use CSS columns, like this:

.vendor-list {
  -webkit-columns: 3;  /* Chrome, Safari, Opera */
  -moz-columns: 3;  /* Firefox */
  columns: 3;
}
@media (max-width: 640px) {
  .vendor-list {
    -webkit-columns: 1;    /* Chrome, Safari, Opera */
    -moz-columns: 1;    /* Firefox */
    columns: 1;
  }
}

<div class="rte">
  <ul class="vendor-list block-grid three-up mobile one-up">
    <li class="vendor-list-item" style="font-size: 20px;">
      <a href="/collections/accessorizeus-com">accessorizeus.com</a>

Answer 2

Add display property:

.vendor-list-item {
  display: inline-block;
  width: 33%;
}

For mobile, use media queries:

@media (max-width: 480px){
  .vendor-list-item {
     width: 100%;
     text-align: center;
   }
}

You could also add a condition for tablets (<767px) to show in 2 columns (width: 50%).
