How to use TiledRowsListLayout with Feathers UI containers

The TiledRowsListLayout class may be used to position items in a data container from left to right, wrapping to multiple rows. All items are positioned within tiles that have the same width and height. This layout supports a number of useful options for the spacing and alignment.

If the layout should divide tiles into pages, instead of scrolling continuously, you may use PagedTiledRowsListLayout instead.

The Basics

Create a ListView container, set its data provider, and add it to the display list.

var container = new ListView();
container.dataProvider = new ArrayCollection([
    {text: "A"},
    {text: "B"},
    {text: "C"}

Set the container's layout property to a new TiledRowsListLayout instance.

By default, the first child will be positioned in the top-left corner. Each additional child will be positioned to the right of the previous child — creating a horizontal row, until the total width exceeds the width of the parent container. Then, the next child will be positioned below the previous children to start a new row.

The following sections will introduce a number of properties that may be used to adjust the positioning and sizing of children in the layout.


The padding is the space around the edges of the container that will contain no children. Padding may be added on each side, including top, right, bottom, and left.

layout.paddingTop = 10.0;
layout.paddingRight = 15.0;
layout.paddingBottom = 10.0;
layout.paddingLeft = 15.0;

If all four padding properties should be set to the same value, call the setPadding() method instead.

// sets top, right, bottom and left to the same value

The gap is the space between items, either horizontally or vertically. The horizontalGap and verticalGap properties are measured in pixels.

layout.horizontalGap = 10.0;
layout.verticalGap = 6.0;

If both gap properties should be set to the same value, call the setGap() method instead.

// sets horizontal and vertical gaps to the same value


The children of the container may be aligned within the container's bounds.

To align the children along the x-axis, set the horizontalAlign property.

layout.horizontalAlign = CENTER;

In the example above, the children are aligned to the center of the x-axis. They may also be aligned to the left or to the right.

To align the children along the y-axis, set the verticalAlign property.

layout.verticalAlign = MIDDLE;

In the example above, the children are aligned to the middle of the y-axis. They may also be aligned to the top or to the bottom.

Note: Vertical alignment may be used only when the total height of the content (including padding and gap values) is less than or equal to the height of the container. If the content is larger than its parent container, the layout will position the children starting from 0.0 on the y-axis, the same as if they were top-aligned.

Rows and columns

If the parent container does not have an explicit height value, the layout will calculate its ideal height automatically. To display a specific number of rows, regardless of the height of each row, set the requestedRowCount property.

layout.requestedRowCount = 4.0;

An integer value is not required, so a partial row may be made visible at the bottom of the list, if desired.

layout.requestedRowCount = 4.5;

If the container contains more children than the number of visible rows, the container will enable scrolling, if supported.

Additionally, the requestedMinRowCount and requestedMaxRowCount properties may be used to specify a range of rows allowed to be displayed, which depends on the number of children added to the container.

Similarly, it's possible to request a specific number of columns for the layout to display. The layout may not always be able to accomodate this value because the container may be too small, but if there is enough room for the requested number of columns, that's the number it will display. Tell the layout to use three columns by setting the requestedColumnCount property:

// unlike rows, columns must be specified as an integer
layout.requestedColumnCount = 3;

Now, the layout will always display three columns, even if the container can fit four or more. However, if only one or two columns can be fit into the container, the layout will display the maximum number that will fit.

If the width of the container is not set, the layout will automatically calculate a width that accomodates the requestedColumnCount.

Additionally, the requestedMinColumnCount and requestedMaxColumnCount properties may be used to specify a range of columns allowed to be displayed, which depends on the number of children added to the container.
