|
<p>Grid lists are an alternative to standard list views. They are best suited for showing data sets
|
|
that represent themselves through images. In contrast to simple lists, grid lists may scroll either
|
|
vertically or horizontally.</p>
|
|
|
|
|
|
|
|
<h2 id="generic_grid">Generic Grids</h2>
|
|
|
|
|
|
<p>The items in a grid list are arranged in two dimensions, one of which is fixed when scrolling
|
|
content. The scrolling direction dictates the ordering of the items within the grid list. Since the
|
|
scrolling direction is not deterministic, make it easy for the user to determine the orientation by
|
|
cutting off grid items to communicate where the overflow is located.</p>
|
|
<p>Avoid creating grid lists that scroll in two dimensions.</p>

<h4>Vertical scrolling</h4>
|
|
<p>Vertically scrolling grid list items are sorted in traditional western reading direction:
|
|
left-to-right and top-down. When displaying the list, cut off the items in the bottom row to
|
|
communicate that the user can scroll the list down to show additional items. Be sure to retain this
|
|
scheme when the user rotates the screen.</p>

</div>
|
|
<div class="layout-content-col span-6">
|
|
|
|
<h4>Horizontal scrolling</h4>
|
|
<p>Horizontally scrolling lists fix the vertical axis of the item grid. Compared to vertically
|
|
scrolling lists, the sorting changes slightly to a top-down and left-to-right arrangement. Employ
|
|
the same technique of cutting off the items in the rightmost column to indicate the scrolling
|
|
direction.</p>
|
|
<p>Don't use scrolling tabs as a means to switch views in conjunction with horizontally scrolling grid
|
|
lists, because the horizontal gesture for view and content navigation will conflict. If you show
|
|
scrolling tabs for view navigation together with a grid list, use vertical grid scrolling for list
|
|
navigation.</p>

<h2 id="with_labels">Grid List with Labels</h2>

<p>Use labels to display additional contextual information for your grid list items.</p>

<h4>Style</h4>
|
|
<p>Use semi-transparent panels on top of the grid list items to display your labels. This allows you to
|
|
control the contrast and ensures legibility of the labels while letting the content "shine through".</p>
