Showing variant name, when only one variant Shopify

You only have one Variant (eg: Size: Large) but this information doesn't appear on the product detail page?

No problem, it's pretty easy to make this display :)

Head over to product.liquid in THEMES > TEMPLATE EDITOR and find line 107:

{% if product.variants.size == 1 %}
<input type="hidden" name="id" value="{{ product.variants.first.id }}" />
{% else %}

Change it to this:

{% if product.variants.size == 1 %}
<input type="hidden" name="id" value="{{ product.variants.first.id }}" />
<p>{{ product.options.first }}: {{ product.variants.first.title }}</p>
{% else %}

Save the file and that's it, your variant information will show on your products detail page (as seen below, 'Color: Leather Oak'.
