The builder has the option to display additional information when the user hovers over an item on the calendar. The second section on the Column Mapping page is used to identify the columns of information to display on hover-over.
The available columns that you selected on the previous page are shown in the Available Columns area. To select a column to include in the hover-over display, highlight it in the Available Columns area and click the right arrow button to move it to the Selected Columns area. Once a column has been selected, you can use the up and down arrow icons to the right to change the order in which they are shown.
There are three Tooltip types offered. The Classic option is normally a good choice as it offers the best compatibility with all column types. If the Advanced option is selected, the Header format and Body format fields can be left blank. Finally, the Basic option is offered for backward compatibility.
