Adding "Select An Option" In Option Drop-Down

[FairTrade4]

Hello Shopify Community,

I know this is a bit advanced, but thought I would reach out for some help.

I am using a paid Shopify theme called Mr. Parker. I would like to add "Select An Option" as the first line that viewers see for the options drop-down. I have read the Shopify articles on how to do this, but it's only for the free themes, and the sections/coding is a bit different on this theme.

This is the bit of code currently on the product-listing liquid:
{% assign current_variant = product.selected_or_first_available_variant %} <span class="variant-sku">{{ current_variant.sku }}</span>
And this is from the product-form.liquid:
{% assign current_variant = product.selected_or_first_available_variant %}

And I know that this might require adding some snippets of code into the js file, this one has "options_selections.js", which is where I think additional changes are required. I can post the code if needed, but thought I would start here for help.

Here is a link to the website, it's still in dev mode: https://swahili-wholesale.myshopify.com/

Any help would be greatly appreciated and can supply additional code snippets if required.

Thanks in advance,

Todd
