Also, here’s the code example they share that is claimed to be 2 columns and responsive and what it looks like on my site, this example is supposed to be 3 columns.
<fieldset>
<legend>column</legend>
<ol class="column">
<ol>
<li> <strong>Ready Class column</strong> </li>
<li> Item1 [text item1a] </li>
<li> Dropdown Menu [select cf7s-menu-01 multiple include_blank "Item1" "Item2" "Item3"] </li>
<li> Item2 [text item2a] </li>
</ol>
<ol>
<li> <strong>Ready Class column</strong> </li>
<li> Item1 [text item1b] </li>
<li> Item2 [text item2b] </li>
<li> Item3 [text item3b] </li>
<li> Dropdown Menu [select cf7s-menu-01 multiple include_blank "Item1" "Item2" "Item3"] </li>
</ol>
</ol>
<ol class="column box">
