This demo uses the function <code>Timeline.setSelection(ids)</code>. Optionally, the window can be moved to the selected items.</p>
<p>  Select item(s): <input type="text" id="selection" value="5, 6"><input type="button" id="select" value="Select"><br>  <label><input type="checkbox" id="focus" checked> Focus on selection</label></p><div id="visualization"></div>
<br/><p>If the height of the timeline is limited some items may be vertically offscreen. This demo uses <code>Timeline.setSelection(ids, {focus: true})</code> and demonstrates that focusing on an item will cause the timeline to scroll vertically to the item that is being focused on. You can use the buttons below select a random item either above or below the currently selected item.</p><button id="prevFocus">Select Item Above</button><button id="nextFocus">Select Item Below</button><br/>
<p>If focusing on multiple items only the first item will be scrolled to. Try entering several ids and hitting <em>select</em>.</p><p>Select item(s): <input type="text" id="selectionVertical" value="g1_5, g2_3"><input type="button" id="selectVertical" value="Select"><br></p>
