Adding a Variable in For Loop Liquid

Is it possible to assign a variable and use that variable in the for loop statement?

I'm trying to place a collection of products in a blog without having to create a new for loop for each article that needs a collection.

What I've done is using the article's tags and splitting just before the collection handle so I can inject it in the for loop, but it's not quite working dynamically yet...

Here's what I've done.. I added in the article tags 

collection_some-page-handle
Then in the article.liquid

    {% for tag in article.tags %}

      {% assign tagMap = tag | split: '_' %}
      {% if tagMap.first == 'collection' %}
        {% assign collectionName = tagMap.last %}
      {% endif %}
    {% endfor %}
    {{collectionName}} <!-- this shows the handle of the collection -->
    {% for product in collections.collectionName.products limit: 8%}
    <div class="productWrap">
            <a href="{{ product.url}}"><img src="{{ product.featured_image | product_img_url: 'medium' }}" alt=""></a>
          <a href="{{product.url}}"><p class="product_title" style="border-top:1px solid #efefef;">{{ product.title | split: ' - ' | first }}</p></a>
    </div>
    {%endfor%}

Now if i try to put the variable in the for loop it doesnt work, but of course if i put the actual handle it works. Is there a way to do it dynamically?

Instead of using collections.collectionName use collections[collectionName].

This should fix your issue if your variable has the proper handle indeed.

To clarify when you use collections.collectionName you say - "Get me a collection that have handle collectionName`.

When you use collections[collectionName] you say - "Get me a collection using the variable collectionName as a handle."
