```
public class DisplayRole
extends Object
```
The Display-Role property describes the role an element plays in the parent algorithm. Seeing that property as general 'LayoutManagerConstraint' might be apropriate.
The RUBY_* properties are required for Japanese and other Asian font support and not yet used.

  - NONE
```
public static final CSSConstant NONE
```
    The element is not rendered. The rendering is the same as if the element had been removed from the document tree, except for possible effects on counters (see [generated] or [paged]).
    Note that :before and :after pseudo elements of this element are also not rendered, see [generated].)
  - BLOCK
```
public static final CSSConstant BLOCK
```
    The element is rendered as a rectangular block. See Collapsing margins for its position relative to earlier boxes in the same flow. In paged media [ref] or inside another element that has two or more columns, the box may be split into several smaller boxes.
  - INLINE
```
public static final CSSConstant INLINE
```
    The element is rendered inside a line box. It may be split into several boxes because of line breaking and bidi processing (see the Text module).
  - LIST_ITEM
```
public static final CSSConstant LIST_ITEM
```
    The element is rendered the same as if it had display-role 'block', but in addition a marker is generated (see 'list-style').
  - RUN_IN
```
public static final CSSConstant RUN_IN
```
    The effect depends on what comes after the element. If the next element (in the depth-first, left to right tree traversal, so not necessarily a sibling) has a 'display-model' of 'block-inside', the current element will be rendered as if it had display-role 'inline' and was the first child of that block element. Otherwise this element will be rendered as if it had display-role 'block'. [Does this explain Ian's tests?]
  - COMPACT
```
public static final CSSConstant COMPACT
```
    The effect depends on the intrinsic size of this element and on what comes after it. If the next element has a 'display-role' of 'block', and the intrinsic width of the compact element is less than or equal to the left margin of that block (resp. the right margin, if the block's 'direction' is 'rtl'), then the compact element is rendered in the left (right) margin of the block at its intrinsic size and baseline aligned with the first line box of the block. [Do we need a different alignment depending on script?] In all other cases the compact element is rendered as if its display-role was 'block'.
  - TABLE_ROW
```
public static final CSSConstant TABLE_ROW
```
    See the Tables module [CSS3TBL].
  - TABLE_CELL
```
public static final CSSConstant TABLE_CELL
```
  - TABLE_ROW_GROUP

    A Pentaho-reporting compatibility setting. Enables the absolute positioning mode.
