Can this be made ?

Hi,

You want to display the Id of the place ?

Hi,

In the file : /components/com_gmapfp/views/tmpl/tmpl_article.php

At the ligne 27, change :
<td class="gmapfp_largeur_titre"><h2><?php echo $row->nom; ?></h2></td>
by
<td class="gmapfp_largeur_titre"><h2><?php echo '<span class="id">'.$row->id.'</span> '.$row->nom; ?></h2></td>
