Bootstrap: comment empiler les divs de différentes hauteurs?

Cette question est un peu similaire à cette une, mais je veux savoir si il est un pur CSS solution compatible avec Bootstrap.

En gros, j'ai le schéma suivant:

Bootstrap: comment empiler les divs de différentes hauteurs?

C'est le HTML de la page:

<div class="menu row">
<div class="menu-category list-group col-lg-3 col-md-4 col-sm-6 col-xs-12">
<div class="menu-category-name list-group-item active">Category</div><a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
<a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
<a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
<a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
<a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
<a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
<a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
</div>
<div class="menu-category list-group col-lg-3 col-md-4 col-sm-6 col-xs-12">
<div class="menu-category-name list-group-item active">Category</div><a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
<a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
<a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
<a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
</div>
<div class="menu-category list-group col-lg-3 col-md-4 col-sm-6 col-xs-12">
<div class="menu-category-name list-group-item active">Category</div><a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
<a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
<a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
<a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
<a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
</div>
<div class="menu-category list-group col-lg-3 col-md-4 col-sm-6 col-xs-12">
<div class="menu-category-name list-group-item active">Category</div><a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
<a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
<a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
<a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
<a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
<a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
<a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
<a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
</div>
<div class="menu-category list-group col-lg-3 col-md-4 col-sm-6 col-xs-12">
<div class="menu-category-name list-group-item active">Category</div><a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
<a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
<a href="#" class="menu-item list-group-item">Lorem ipsum.<span class="badge">€ 0.00</span></a>
</div>
</div>

Le problème est, comme vous pouvez le voir, que la ligne du système de Bootstrap est un peu gênant ici. Je veux que ces catégories de pile dans la manière la plus optimale.
Donc ma question est: comment puis-je le faire avec du CSS? La maçonnerie plugin semble excellent, mais je voudrais le garder pour le plan B.

Merci!
