`onItemRemove` _Function_ **optional** A method to be called whenever an item is removed by the user. It will be passed 2 parameters: the item removed, an updated array of selected items. Example:

_handleItemRemoved (item, selectedItems) {
  console.log(item + ' was removed from the list');
}

<TypeAhead
  // ..other props
  onItemRemove={_handleItemRemoved)
/>

`onItemSelect` _Function_ **optional** A method to be called whenever an item is selected by the user. It will be passed 2 parameters: the item selected, an updated array of selected items. Example:

_handleItemSelected (item, selectedItems) {
  console.log(item + ' was selected from the list');
}

<TypeAhead
  // ..other props
  onItemSelect={_handleItemSelected)
/>

`placeholderText` _String_ **optional** Default: 'Select Filters' The text to display by default when no items have been selected.
`preSelectedItems` _Array_ **optional** An array of Strings to be displayed as selected options by default. These values should be contained in the `items` Array. These values will be the starting point of the TypeAhead's selected values state. Once the user begins interacting with the TypeAhead, they will be ignored.
