Flow Boxes

../_images/flow-box.png

Flow boxes provide a generic grid container which can be used to arrange controls or content items. They can be used for the main view of an application or for laying out smaller areas. Examples of flow box usage include:

  • a background chooser, with a grid of images from which the user can select

  • a tool palette, with a grid of toggle buttons

  • a document browser, with a grid of document thumbnails

Flow boxes are suitable for relatively small static grids. For very large, dynamic grids, see grid views.

General Guidelines

The following guidelines primarily apply to cases where flow boxes are used to present a grid of content items, as opposed to controls:

  • Wherever possible, each grid item should have a unique thumbnail.

  • Order the items in the grid according to what will be most useful to users. Ordering content according to most recently added is often the best arrangement.

  • The visual styling of the grid should be appropriate to the type of content being displayed. In general, the goal should be to minimize visual distractions and allow the content itself to shine. However, in cases where grid images have irregular shapes or inconsistent appearance, it may be necessary to outline each grid cell.

  • Grids and list layouts can be combined, to offer different views of the same content collection. An alternative list view can be useful for displaying additional metadata associated, such as creation dates or authorship.

  • Most grids will be contained within resizable windows, and should therefore be tested to ensure they look good at the range of expected window sizes screen resolutions. Often, flow boxes should be given a maximum width, in order to prevent uncomfortably long rows or the grid reflowing to a small number of rows.
