The igTreeGrid includes a Tooltips feature which allows tooltips to appear when the user hovers the mouse pointer over a grid cell. Tooltips are configurable to adjust duration and visibility options. Further information regarding the classes, options, events, methods and themes of this API are available under the associated tabs above.
