Full height columns on Foundation

Question

I'm using Foundation 5 Framework and need to create 3 same height columns.

Second columns includes 2 panels, I need to stretch all columns to full height (in the second columns there will be just second panel stretched to full height).

Any idea? I don't want to use block grid for this.

My code:

<div class="row">
  <div class="small-12 medium-4 columns">
    <div class="panel">
      <!-- here comes the content--->
    </div>
  </div>
  <div class="small-12 medium-4 columns">
    <div class="panel">
      <!-- here comes the content--->
    </div>
    <div class="panel">
      <!-- here comes the content--->
    </div>
  </div>
  <div class="small-12 medium-4 columns">
    <div class="panel">
      <!-- here comes the content--->
    </div>
  </div>
</div>

For anyone else looking for this, this is now built in to Foundation as Equalizer http://foundation.zurb.com/docs/components/equalizer.html

From their docs:

You can create an equal height container using a few data attributes. Apply the data-equalizer attribute to a parent container. Then apply the data-equalizer-watch attribute to each element you'd like to have an equal height. The height of data-equalizer-watch attribute will be equal to that of the tallest element.

<div class="row" data-equalizer>
  <div class="large-6 columns panel" data-equalizer-watch>
    ...
  </div>
  <div class="large-6 columns panel" data-equalizer-watch>
    ...
  </div>
</div>
