# rc-searchselect

This is a React search selection control that supports complex data selection callbacks. The selected data is an object, and this object is user-defined and supports setting and emptying operations. There is also an important feature that introduces a react-virtualized control that solves the problem of rendering jams in millions of data source scenarios.
