React Nice Dates is composed of a set of components and utilities with different levels of abstraction that you can use to build your own date pickers.
At the top level, you have
DateRangePicker. These are slightly-opinionated components that should cover the most common use-cases. They allow displaying date inputs with a calendar popover below. They make no assumptions about how your inputs should look. Instead, they provide all the necessary props so you can render them yourself.
