Hi Margaret-
Whether you decide to start over or make improvements, I highly recommend working in a staging environment like Cloud WordPress.
If you decide you’d like to try and update what you have already, you can copy your existing site to staging with these instructions. Once you’re happy with it, you can deploy it back to your productions site with these instructions.
It looks like your son started your website with BoldGrid Inspirations, using the “Diced” theme. If you’re looking to start over, you can create a new BoldGrid Inspirations site with Cloud WordPress too.
Here’s our guide on working with your Navigation Menus. Scroll about halfway down to find the section on creating drop-down menus.
I know it seems overwhelming to make the decision, but using Cloud WordPress you won’t have to worry about breaking what you already have while you experiment, so there’s no stress in trying it out and seeing what possibilities you have.
Hopefully this helps, please let us know if you need any help along the way. We’re happy to help.
