Under some circumstances, we've discovered a bug in version 1.0 of the Galleria theme where the mega menu will appear as one long single-column drop-down menu instead of spread across the page in multiple columns. If you are experiencing this issue, please follow these steps to fix it:

• Login to your Shopify dashboard
• Go to Online Store > Themes > Galleria
• Click the Actions button and then Edit Code
• Navigate to the Snippets folder and open the file called navbar-mega.liquid
• Around line 152 of this file, you will see

  {% if size_of_grand_child_sum == 0 %} {% assign grandChildLinksQty = "no-child-links"%} {% endif %}

• Replace that with:

  {% if size_of_grand_child_sum == 0 %} {% assign grandChildLinksQty = "no-child-links"%} {% else %} {% assign grandChildLinksQty = nil %} {% endif %}

• Save the file and the issue should disappear.
