Hello,

If you want to display a tooltip when the user hovers the mouse pointer over the drop-down list, press the down arrow to select the property that you want to display as a tooltip or type a text string within quotations, for example, "Select to open an item".This tooltip applies to the entire drop-down list. If the List Source Type is Data page, Clipboard page or Report definition, you can also specify a tooltip that displays when the user hovers the mouse pointer over an item within the drop-down list. To do this, specify the Property for tooltip in the List Source area on the General tab.
