<FuzzySearch
      list={list}
      keys={['author', 'title']}
      width={430}
      onSelect={(newSelectedItem) => {
        // Local state setter defined elsewhere
        setSelectedItem(newSelectedItem)
      }}
    />

Custom Result Template

<FuzzySearch
  list={list}
  keys={['author', 'title']}
  width={430}
  onSelect={(newSelectedItem) => {
    // Local state setter defined elsewhere
    setSelectedItem(newSelectedItem)
  }}
  resultsTemplate={(props, state, styles, clickHandler) => {
    return state.results.map((val, i) => {
      const style = state.selectedIndex === i ? styles.selectedResultStyle : styles.resultsStyle;
      return (
        <div
          key={i}
          style={style}
          onClick={() => clickHandler(i)}
        >
          {val.title}
          <span style={{ float: 'right', opacity: 0.5 }}>by {val.author}</span>
        </div>
      );
    });
  }}
/>

Options

attribute	default	description
caseSensitive	false	Indicates whether comparisons should be case sensitive.
className	null	give a custom class name to the root element
inputProps	{}	Props passed directly to the input element. i.e. defaultValue, onChange, etc.
inputStyle	{}	Styles passed directly to the input element.
inputWrapperStyle	{}	Styles passed directly to the input wrapper div.
isDropdown	false	Hide the result list on blur.
listItemStyle	{}	Styles passed to each item in the dropdown list.
listWrapperStyle	{}	Styles passed directly to the dropdown wrapper.
selectedListItemStyle	{}	Styles passed directly to current 'active' item.
width	430	width of the fuzzy searchbox
distance	100	Determines how close the match must be to the fuzzy location (specified by location). An exact letter match which is distance characters away from the fuzzy location would score as a complete mismatch. A distance of 0 requires the match be at the exact location specified, a distance of 1000 would require a perfect match to be within 800 characters of the location to be found using a threshold of 0.8.
id	null	The name of the identifier property. If specified, the returned result will be a list of the items' identifiers, otherwise it will be a list of the items.
include	[]	An array of values that should be included from the searcher's output. When this array contains elements, each result in the list will be of the form { item: ..., include1: ..., include2: ... }. Values you can include are score, matches. Eg: { include: ['score', 'matches' ] }
maxPatternLength	32	The maximum length of the pattern. The longer the pattern, the more intensive the search operation will be. Whenever the pattern exceeds the maxPatternLength, an error will be thrown.
onSelect	noop	Function to be executed on selection of any result.
keyForDisplayName	title	The key which should be used for list item text.
keys	all[Array]	List of properties that will be searched. This also supports nested properties.
list	null	Array of properties to be filtered.
maxResults	10	Max number of results to show at once.
placeholder	'Search'	Placeholder of the searchbox
resultsTemplate	Func	Template of the dropdown divs
shouldShowDropdownAtStart	false	Allow the searchbox to act as a filter dropdown with initial values. Yields all results when the search value is blank.
shouldSort	true	Whether to sort the result list, by score.
sortFn	Array.prototype.sort	The function that is used for sorting the result list.
threshold	0.6	At what point does the match algorithm give up. A threshold of 0.0 requires a perfect match (of both letters and location), a threshold of 1.0 would match anything.
tokenize	false	When true, the search algorithm will search individual words and the full string, computing the final score as a function of both. Note that when tokenize is true, the threshold, distance, and location are inconsequential for individual tokens.
verbose	false	Will print to the console. Useful for debugging.
