@thebeadfarm of course! No problem. It's very simple to do and won't affect your current site. In your Themes section of your admin, you'll see the name of your themes. If you've renamed them, you can see what the theme's original file name was by going to Customize > Theme actions. It will look similar to this:
Once you have the name of the theme you can download a new copy in the theme store.
When you download any new themes to your account, none of them will replace the one you have published. What will happen is that they will show up in your Themes section so you can edit and work on them freely before you publish them. So you can test things out with any themes in there without worrying that they will show up live on your site. If you want to publish one of them as your official site theme you can follow the steps here to do that, but you won't see that theme on your site until you follow those specific steps.
Thanks for trying that, @thebeadfarm! Since you're using our Shopify Debut theme, what we're going to need to do is dive into your theme to see what is happening. As long as you haven't done any code changes or any apps that modified your code, we can have our theme specialists take a peek. To do that we will need to escalate a ticket to that team.
To open a new ticket we’ll need to access your account in order to resolve this issue. While we’re not able to provide account-specific support via the Shopify Community at this time, we’d be happy to continue assisting you through live chat, email, or callback. Please visit https://bit.ly/3cJkx8V and log in to your account to create a support request.
In order to save some time, and help the Support Advisor you speak with to pick up from where you and I have left off, I am going to provide you with a summary of the issue as I understand it. You can share this summary at the beginning of your conversation with the agent to bring you both up to speed and help to get your answers as quickly as possible.
Issue Summary: Debut theme's drop-down menus not expanding as expected
Once the escalated ticket is in the queue for the escalated team, you'll be in touch with our theme specialists via email.
