Being a successful theme-maker is all about giving your users the ability to customize. Luckily for us, tumblr makes it easy for us theme-makers to do that!
Learning to implement drop down lists in your theme will give your users easy control and a variety of options for their theme. (It also protects you from having to use several checkboxes to toggle through different options for the same element!) I haven’t seen many theme makers include these as of yet, so I’m hoping this tutorial will help a few people out!
