<info><![CDATA[

TableTools provides the ability to group buttons into a hidden drop down list, which is activated by clicking on a top-level button. This is achieved by extending the 'collection' predefined button type and setting it's `aButtons` parameter with the same options as the top level buttons (note that you cannot currently use a collection within a collection).

The example below shows the file save buttons grouped into a collection, while the copy and print buttons are left on the top level.
