Select the Toggle Button part to add a control that resembles a check box. A toggle button represents a choice with two clearly distinguishable states: on and off. Toggle buttons are typically used in a group to provide a multiple-choice field.
When a user selects the choice, the toggle button indicates that the choice is selected. The user can clear the toggle button by selecting the choice again, thereby deselecting the choice.
To display the pop-up menu for the part, click with mouse button 2 on the part.
To further define the appearance and function of a part, double-click on it to open the properties window.
