React Cool Virtual is a lightweight and performant virtualization library for React. It helps optimize the rendering of large lists or grids by rendering only the visible items, resulting in improved performance and reduced memory usage. It leverages the power of React's hooks and uses a windowing technique to efficiently handle large datasets.

React-virtualized-select npm package is a customisable, lightweight and powerful select component that leverages React's virtualisation techniques to render a high-quality user interface. In particular, react-virtualized-select is a fork of the popular library react-select which is adapted to work efficiently with very large lists. The package offers several of the features in the react-select package, including multi-selection, search functionality and autocomplete functionality, in addition to some other customisations like resizing.

Both react-cool-virtual and react-virtualized-select are libraries that provide virtualization capabilities, allowing efficient rendering of large lists or dropdowns in React applications. However, there are some differences in terms of functionality.


react-cool-virtual is a lightweight library that focuses on virtualizing lists. It provides a simple API and supports features like dynamic item heights, sticky items, and smooth scrolling. It does not have built-in support for dropdown menus.

Dropdown Support

On the other hand, react-virtualized-select is specifically designed to handle virtualization of dropdown menus. It is built on top of react-virtualized and provides a customizable dropdown component with search functionality, keyboard navigation, and multi-select support.


Both libraries offer customization options, but react-cool-virtual provides more flexibility in terms of styling and rendering. It allows you to customize the appearance and behavior of the virtualized list according to your specific needs. react-virtualized-select also offers some customization options, but it is more opinionated in terms of UI.


Both libraries aim to improve performance by rendering only the visible elements. However, react-cool-virtual is known for its efficient rendering of large lists with minimal re-renders. It uses a dynamic windowing technique to ensure smooth scrolling. react-virtualized-select also provides good performance for dropdown menus with a large number of options, but it focuses more on the dropdown functionality rather than optimizing list rendering.

Community and Maintenance

Both react-cool-virtual and react-virtualized-select have active communities and are well-maintained. However, react-virtualized-select is based on react-virtualized, which is a popular and mature library for virtualization in React. This means that react-virtualized-select benefits from the stability, reliability, and ongoing development of react-virtualized.
