I’ve always had great luck with WebListBoxStyleRenderer, and using Cell.Tags to store useful information to make clicking in cells ‘smart. Now I wondering about adding mouse-over ‘tooltip’-like behaviors to cell contents. Essentially having a mouse-over event that renders a small dialog (tooltip?) when passing over a cell. Using the image below as an example, to mouse-over the truck or plane to show more info, without having to click the cell. Suggestions? (thanks!)

This needs to be implemented browser side with JavaScript and not server side with a mouse event. Greg removed mouse events from Web 2.0 _on purpose_ and Ricardo has been slowly giving in and putting them back.

It would be a negative impact on Xojo Web to see mouse events on a per cell level. That will cause so much traffic.

If you’re rendering html for your cells, just add a title attribute. That’s probably the easiest way to get a tooltip quickly.
