Custom Select Dropdown

A customizable select element that works cross-browser.

The custom select menu is some helpful HTML & CSS for when you need a non-default select menu styled for a design. This does not include the open menu state. If that needs styling you will have to evaluate a plugin like Selectize or Chosen. Both are fine options.
