list shopify collections based on a menu

{% comment %}let's build a list of collections based on a menu of collections.{% endcomment %}   
{% comment %}this can be added to a page or collection - I'm assuming collection.{% endcomment %}   

{% comment %}to start you need a menu which contains a list of links to collections.{% endcomment %}
{% comment %}this is a barebones version - which is supposed to be pulled into a theme so edit grid/loop etc as required{% endcomment %}   
{% comment %}for custom shopify theme development email design at liquid dot gallery {% endcomment %}   

{% comment %} our menu of collections has the handle "in-wild" {% endcomment %}   

{% assign mastercollection = collection %}    {% comment %}don't need this if using a page - use it to escape the for loop and reassign original collection.{% endcomment %}
