ReactJS Evergreen Autocomplete Component

React Evergreen is a popular front-end library with a set of React components for building beautiful products as this library is flexible, sensible defaults, and User friendly. Autocomplete Component is used for auto-completing the free text value with the option value. It basically allows the user to type and select the item from a list of options. We can use the following approach in ReactJS to use the Evergreen Autocomplete Component.

• items: It is used to denote an array of items to be used as options for the selection.
• selectedItem: It is used to denote the selected Item to be shown on the Autocomplete.
• itemToString: It is a function that is used on each item to return the string that will be shown on the filter in case the array of items is not an array of strings.
• children: It is a function that is used to render the ‘filter’ component.
