描述

Hey guys,

it is possible to hide or remove an empty dataset from the DOM? I ask because my datasets have a bottom border and if without any results it renders 4 empty dataset div's.

研究方向
The issue requests an option to hide or remove empty dataset containers from the DOM. Start by examining how datasets are rendered in the typeahead.js source code, likely in files like `src/typeahead/dataset.js` or similar. Look at the code that appends dataset elements to the DOM and see if there is a condition to check for empty results. You may need to add a configuration option (e.g., `hideEmpty`) and modify the rendering logic to not display or to hide the dataset container when there are no suggestions. Check the existing comments or linked issues for any prior discussion on this feature (none found in this issue). Testing should ensure that the DOM does not contain empty dataset divs when no results are present.
