KML with selectable POI

tmtck015 years ago

I need my POIs contained within the KML file to be clickable with popup (info window)
I'm using a simple KML file for testing:

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2">
  <Placemark>
    <name>Description with html</name>
    <description><![CDATA[
      <h1>HTML is possible within a description</h1>
      Some <span style='color:red'>red text</span>.      
      <table border=1>
        <tr><td>one  </td><td>foo</td></tr>
        <tr><td>two  </td><td>bar</td></tr>
        <tr><td>three</td><td>baz</td></tr>
      </table>
    ]]></description>
    <Point>
            <coordinates>8.542952335953721,47.36685263064198,0</coordinates>
    </Point>
  </Placemark>
</kml>

but, clicking on the marker has no effect

what could be the problem ?
