An element that displays only one of its children at a time. The index attribute determines which child is displayed.

Attributes inherited from XUL Element

Determines the horizontal alignment of the children of the deck.

• left: The elements are aligned on their left edges.
• center: The elements are centered.
• right: The elements are aligned on their right edges.

In the deck is placed inside a horizontally oriented box, autostretch determines whether the deck stretches vertically to fit the given space. For vertically oriented boxes, determines whether the deck stretches horizontally to fit the given space. Stetching in the opoosite direction is controlled with the flex attribute.

• never: The deck is never stretched and is displayed at the size specified by its width and height attributes or by the CSS width and height properties.
• always: The deck stretches to fill the given space.

If true, then the deck is collapsed and does not appear. It is equavalent to setting the CSS visibility property to collapsed.

If the label of the deck is too small to fit in its given space, the text will be cropped on the side specified by the crop attribute. An ellipsis will be placed in place of the cropped text.

• left: The text will be cropped on its left side.
• right: The text will be cropped on its right side.
• center: The text will be cropped on both sides.
• none: The text will be not be cropped using an ellipsis. However, the text will simply be cut off if it too large. The side depends on the CSS text alignment.

If true, extra borders are drawn around the element and all its descendants. This can be used to determine orientation and where flexible elements are. If debug mode is enabled for a box, horizontal oriented boxes are displayed with a blue border and vertical boxes are displayed with a red border. The border above the element will be straight for non-flexible elements and wavy for flexible elements.

Indicates the flexibility of the deck. Flexible elements grow and shrink to fit their given space. The actual value is not relevant unless there are other flexible elements with-in the same container. Elements with larger flex values will grow more than elements with lower flex values, at the ratio determined by the two elements.

The height of the deck in pixels. It is recommended to use the CSS height property instead.

• vertical: Child elements of the deck are placed under to each other in a column in the order that they appear in the XUL source.

For elements placed within a bulletinboard, specifies the position of the top edge of the deck.
