This is a layout library for Enyo 2. This library provides a collection of layout functionality


The list package provides a List control that displays a scrolling list of rows. It's suitable for displaying very large lists and is optimized such that only a small portion of the list is rendered at a given time.

Check out the List samples in the Layout section of the Enyo Sampler to see the control in action. For more information, see the List documentation in the Enyo Developer Guide.


The fittable package helps you create layouts that expand to fit available space--a common need for apps, but one that has historically been difficult to meet using Web technologies.

The FittableColumns and FittableRows controls let you define views whose children are arranged either horizontally or vertically. Within a given view, you can designate one child to expand and contract to fit the available space, while its siblings retain their natural or explicitly-specified sizes. Fittable views may be nested as needed.

If you're thinking that this sounds a lot like a limited version of the CSS Flexible Box Model, you're right. Our main objective was to provide a layout model with capabilities similar to Flex Box, but with greater browser compatibility. We also wanted to impose as few limitations as possible on the CSS styling of child components, and to use JavaScript sparingly (we use it to calculate the height of fittable elements, but otherwise leave the layout work to the browser).

As much as we like them, we want to emphasize that you should only use FittableColumns and FittableRows when you need views to expand and contract to fit available space. If you simply want to arrange elements horizontally or vertically, you're better off employing standard Web layout techniques.

Check out the Fittable sample to see FittableColumns and FittableRows in action.


The enyo.Panels kind is designed to satisfy a variety of common use cases for application layout. Using enyo.Panels, controls may be arranged as (among other things) a carousel, a set of collapsing panels, a card stack that fades between panels, or a grid.

For more information, see the Panels documentation on the Enyo wiki.


Slideable is a control that can be dragged either left-to-right or up-and-down between a minimum and a maximum value. When released from dragging, a Slideable will animate to its minimum or maximum position based on the direction dragged.


Tree is a control showing a vertical list of labels with nesting and collapsing of hierarchy levels. There's a simple example in the Enyo Sampler showing the control in use as a directory and file tree.
