You can create a dialog box to display a list in your App using the CreateListDialog method of the app object:
Use the SetOnTouch method of the ListDialog object to set the name of a function you want to be called when a list item is selected. The selected item is passed into your OnTouch callback function as parameters every time an item is selected.
You can use the "Multi" option to create a ListDialog with check boxes against each item. This allows multiple list items to be selected. An extra parameter isChecked is passed to the OnTouch callback function when a check box is checked or unchecked.
When using the "Multi" option, the ListDialog can be dismissed using the back button on the phone or tablet.
