<!-- explanation copy -->
<div class="explanation">
<p>In this example, an instance of the <a href="../reference/Uize.Widget.Collection.Dynamic.html"><code>Uize.Widget.Collection.Dynamic</code></a> widget class is being used to wire up an editable grid of photos. You can select items in the grid by clicking on them. You can make a non-contiguous selection by ctrl-clicking on items. You can make a range selection by clicking on one item and then shift-clicking on another. Use the "<b>SELECT NONE</b>" button above the grid to clear a selection, or use the "<b>SELECT ALL</b>" button to select all the items. With some items selected, click the "<b>REMOVE</b>" button to remove the selected items. Also with a selection, click-and-drag to reposition the selected items within the collection.</p>
<p>Each item in the grid utilizes the <a href="../reference/Uize.Widget.CollectionItem.html"><code>Uize.Widget.CollectionItem</code></a> widget class. This limited utilization of the <code>Uize.Widget.Collection.Dynamic</code> class is not connected up to an application, so there are no consequences to reordering or removing items. To restore the grid contents, just <a href="collection-dynamic.html">reload the page</a>.</p>
