Motivation
Most computer displays are wider than they are high. So to take advantage of this you sometimes want to grow form data to the right, not down. To do this you must add CSS instructions to use an "inline" display for items within a repeat.
Method
CSS has two "display" options:
display:blockadds new elements vertically so the left edge is aligned.display:inlineis horizontal placement where new divs gets added to the right just like new text is added to an input field.
The new elements get added to the current row. By default XForms used a block repeat. But this can be easily changed with a two stylesheet command.
In FireFox the class to modify the attributes of the repeated item is .xf-repeat-item. Other XForms players may use a different CSS element.
/* Makes the repeated items get added to the right. */
.xf-repeat-item {display:inline;}
/* We MUST put this in to limit the width of the repeated item */
.xf-repeat-item .xf-value {width: 70px;}

Discussion
In the example above we note that the widths of each cell is determined by the size of the label. Each cell can have a different label. Note that we create a wrapper for each cell using a div. Both the cell wrapper and the .xf-fepeat-item must be set to be display:inline.
Adding Two Dimensional Nesting
You can nest repeat groups to create grids of cells. Just make the outer repeat have class attribute to adjust the line height.

CSS
The following CSS will be needed to display a each row on a new line:
.row {
display:block;
line-height: 50px;
}
Scoreboard Example
The following example shows how you can put text in before and after the inner repeat.
