Change Dropdowns to “Select2” Version

I have WooCommerce installed, and a number of plugins associated with it- Measurement Price Calculator & TM Extra Product Options mainly. Using those plugins, I’ve created a dropdown box with a ton of options- too many for a typical dropdown select box. I’ve noticed the Select2 dropdown box included with WooCommerce has a text box to search and filter the contents built into the select field. I’d like to use this version, but I don’t know how to do that. The Select2 version isn’t the most appropriate for all dropdowns, but if it’s easier to go with it by default for all, I’d take that solution over picking through code for every dropdown individually. Any questions, please ask.
