 * @name RefinementList
 * @kind widget
 * @propType {string} attribute - the name of the attribute in the record
 * @propType {boolean} [searchable=false] - true if the component should display an input to search for facet values. <br> In order to make this feature work, you need to make the attribute searchable [using the API](https://www.algolia.com/doc/guides/searching/faceting/?language=js#declaring-a-searchable-attribute-for-faceting) or [the dashboard](https://www.algolia.com/explorer/display/).
 * @propType {string} [operator=or] - How to apply the refinements. Possible values: 'or' or 'and'.
 * @propType {boolean} [showMore=false] - true if the component should display a button that will expand the number of items
 * @propType {number} [limit=10] - the minimum number of displayed items
 * @propType {number} [showMoreLimit=20] - the maximum number of displayed items. Only used when showMore is set to `true`
 * @propType {string[]} [defaultRefinement] - the values of the items selected by default
 * @propType {function} [transformItems] - Function to modify the items being displayed, e.g. for filtering or sorting them. Takes an items as parameter and expects it back in return.
 * @themeKey ais-RefinementList - the root div of the widget
 * @themeKey ais-RefinementList--noRefinement - the root div of the widget when there is no refinement
 * @themeKey ais-RefinementList-searchBox - the search box of the widget. See [the SearchBox documentation](widgets/SearchBox.html#classnames) for the classnames and translation keys of the SearchBox.
 * @themeKey ais-RefinementList-list - the list of refinement items
 * @themeKey ais-RefinementList-item - the refinement list item
 * @themeKey ais-RefinementList-item--selected - the refinement selected list item
 * @themeKey ais-RefinementList-label - the label of each refinement item
 * @themeKey ais-RefinementList-checkbox - the checkbox input of each refinement item
 * @themeKey ais-RefinementList-labelText - the label text of each refinement item
 * @themeKey ais-RefinementList-count - the count of values for each item
 * @themeKey ais-RefinementList-noResults - the div displayed when there are no results
 * @themeKey ais-RefinementList-showMore - the button used to display more categories
 * @themeKey ais-RefinementList-showMore--disabled - the disabled button used to display more categories
 * @translationkey showMore - The label of the show more button. Accepts one parameters, a boolean that is true if the values are expanded
 * @translationkey noResults - The label of the no results text when no search for facet values results are found.
 * @requirements The attribute passed to the `attribute` prop must be present in "attributes for faceting"
 * on the Algolia dashboard or configured as `attributesForFaceting` via a set settings call to the Algolia API.
 *
 * If you are using the `searchable` prop, you'll also need to make the attribute searchable using
 * the [dashboard](https://www.algolia.com/explorer/display/) or using the [API](https://www.algolia.com/doc/guides/searching/faceting/#search-for-facet-values).
 * @example
 * import React from 'react';
 * import algoliasearch from 'algoliasearch/lite';
 * import { InstantSearch, RefinementList } from 'react-instantsearch-dom';
 *
 * const searchClient = algoliasearch(
 *   'latency',
 *   '6be0576ff61c053d5f9a3225e2a90f76'
 * );
 *
 * const App = () => (
 *   <InstantSearch
 *     searchClient={searchClient}
 *     indexName="instant_search"
 *   >
 *     <RefinementList attribute="brand" />
 *   </InstantSearch>
 * );
