Has 'All' option
The Has 'All' option places an 'All' button at the end of your alphabet. Users can click this button to bring them back to a main grid that displays everything listed under the different letters in one long list. The list can have multiple pages to it. You can change the text on the All button using the 'All' option label property. If you do not want an 'All' button simply uncheck the checkbox next to the Has 'All' option property.
