| 31 | * <p> | |
| 32 | * Although a table based template could be used, setup is done to also support | |
| 33 | * a CSS based template. The items in the <code>Container</code> instance are | |
| 34 | * rendered sequentially wrapping each one with a span element. The padding | |
| 35 | * property can be configured to space the elements as needed. To achieve a | |
| 36 | * vertical orientation, the span style is set to block. Additional styling can | |
| 37 | * be set for the items by using the itemSpanStyle property. | |
