I have an installation of Magento 2.2.6 with a purchased theme enabled on my web store. On some of my products, I want the customer to be able to select a date and time range in the Customizable Options. Currently, when I use the default Date and Time options, the frontend is ugly and difficult to use. When I browse the Magento documentation, I see there is support for pretty, user-friendly DateTime controls.
Can someone offer some guidance on how I implement this on my product? I think I may need a custom module, but I'm unfamiliar with the process and I don't know what file(s) to edit/add. Can someone explain how I can figure out which file(s) to edit/add so I follow best practices to make the DateTime picker controls work? I'd like to get an understanding of how/why to use a custom module. Is my custom module 'layered' on top of my custom theme? How does Magento know which layer is on top?
My goal is to implement the Date and Time Range Picker. Thanks in advance for any help.
