title: Scrollable Card bootstrap
body: <p>I am using bootstrap 4. I have 3 columns in a single row. One of the columns contains a list and the other two do not. I want only the column with the list to be scrollable but not the entire container, which means that the scrollbar muss appear only within that column.</p>
  
  <p>I would appreciate any help.</p>
  
  <pre><code>&lt;div class="row"&gt;
  &lt;div class="col-sm-4"&gt;
    &lt;div class="card"&gt;...
  
  &lt;div class="col-sm-4"&gt;
    &lt;div class="card"&gt;...
  
  &lt;div class="col-sm-4"&gt;
    &lt;div class="card"&gt;...
  
  &lt;/div&gt;
  </code></pre>
