<p>
This example groups regional sales records by region, country, and channel.
The grouped columns are hidden so the sticky group path is easier to follow while you scroll:

<div class="demo-options">
<label class="checkbox-inline">
<input id="stickyGroupHeaders" type="checkbox" checked>
Sticky group headers
</label>
</div>
<p class="demo-note">
Basic usage: set <code>stickyGroupHeaders</code> to <code>true</code> on a grouped
FlexGrid to keep the active group path visible while you scroll through the rows.
