This widget isn't actively supported, please use the better alternative: 'Bootstrap Tooltip' widget, for this purpose instead. Because this widget is used a lot, we decided to create a MX6 version, but we will not actively support this widget
The Help Text Viewer provides the possibility to enhance your forms by adding help buttons. These buttons display a help message when clicked or hovered.
Optionally, the buttons can be hidden by default, with a global switch (the Help Text Trigger) to show or hide them.
