<div class="info">
<p>
<i>ol/control/FeatureList</i> is a control for displaying features in a list.
</p>
<p>
The list is optimzed to display large datasets in the table.
</p>
<ul>
<li>
You have to define a <i>ol/source/Vector</i> or a list of feature to display in the table.
</li>
<li>
The control use optimization to display large dataset, only visible rows (page) are displayed in the table.
<br/>
Set the <i>pageLength</i> property to enlarge visible rows size (default 200 rows).
</li>
<li>
The list can be ordered and sized by the user.
</li>
<li>
Use the <i>select</i> (or <i>dblclick</i>) event to acknowledge of a clik on a row (cell).
</li>
</ul>
