 ### The `titleText` Function
 
 The `titleText` parameter accepts a function that takes an object that contains one of the items from the data set and returns a string to display as the title, next to the collapse/expand button. The object, at the moment, contains only one parameter, `item`, which is the item for which the title will be displayed.
