Description from Webflow:
Update 02-12-2020: -Added color variable for list option (in dropdown) text color on hover -Added color variable for selected option text color that displays in the field after it's selected A cloneable project using the Nice-Select JQuery plugin to style and customize a <select> field in your Webflow project. I made the customization process really easy. In the Navigator you will see a custom code element called "style-settings". Open that up and you will see the different options for Color and Spacing. Comments are used as well so you know which does what. Simply copy and paste in your own color and spacing values. Last, we need to initiate the the plugin by copying the simple script code that is located in the Page Settings > Custom Code > </body>. You can also add that code and the <style> code to your Sites Settings Custom Code (global) so it translates across your entire site for all forms that have a <select> input field. Hope you dig it and of course I hope it helps!
