Are there any apps that will make a dropdown showcasing different fonts - not just their names?

Essentially the title. I'd like to add an app that will allow customers to choose which font they want to use. Instead of just making a dropdown with the one standard font displaying all the font options, in name alone, I'd like the dropdown itself to reflect the font options - using the actual fonts to make up the dropdown options. I hope that was clear.

Thank you!
