Creating tooltips for App Builder projects
App Builder does not innately have the option to produce tooltip help for components and
other elements of App Builder projects. The Label component, however, does provide for the
implementation of tooltips in the App Builder project UI.
Tooltips are bits of text that display when the cursor hovers over a component or other element in the user interface. To create a UI for your App Builder app that uses tooltips, you can replace built-in component labels with actual Label components. Then, on the Content tab of the Properties panel, set the Label component's Label value to the original component's label text and provide the Tooltip value.
