  • Last Updated : 05 Jun, 2021

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. Combobox Component allows the user to select an option from a predefined list of options. We can use the following approach in ReactJS to use the Combobox Button Component.

Combobox Props:

  • item: It is used to denote the options to show in the menu.
  • selectedItem: It is used to denote the selected item when controlled.
  • onChange: It is a function that is called when value changes.
  • openOnFocus: It is used to open the autocomplete on focus when this is set to true.
  • initialSelectedItem: It is used to denote the default selected item when uncontrolled.
  • placeholder: It is used to denote the placeholder text.
  • 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.
  • inputProps: It is used to denote the properties forwarded to the input.
  • buttonProps: It is used to denote the properties forwarded to the button.
  • autocompleteProps: It is used to denote the properties forwarded to the autocomplete component.
  • disabled: It is used to make the input element disabled.
  • isLoading: It is used to show a loading spinner when this is set to true.
  • size: It is used to denote the size of the component.
