Yes, for that use a <select> element, it's this part in LineWeb.htm :

			<table>
				<tr>
					<td>Build:</td>
					<td>
						<select id="Build">
							<option value="lines">Lines</option>
							<option value="polylines">Polylines</option>
							<option value="curves">Curves</option>
							<option value="points">Points</option>
						</select>
					</td>
				</tr>
			</table>

If you give the select element an id value then when it is changed it will generate a UI event of that name in the script's event loop.

Or you can also put in script code in the .htm file using an onchange="" handler, something like:

        <select id="Build" onchange="moi.ui.alert( 'changed' );">

Let me know if you're still stuck on this part.
