    <p>I'm attempting to make a Google Map which allows the user to check off a category and have those specific locations display. I've got that part working:</p> <p><a href="http://thedenvillehub.com/test-hs/adv/scripts/test.html" rel="nofollow">http://thedenvillehub.com/test-hs/adv/scripts/test.html</a></p> <p>What I want to do is have a different icon come up for each category, so that one is red, one is blue, etc. I found a couple of examples online but nothing seems to be working for me. Here's my code for reference:</p> <pre><code>var markers = new Array(); var locations = [ ['Boonton Town', '402-9410', 'Dial-a-Ride', 40.902, -74.407, 1 ], ['Boonton Township', '331-3336', 'Dial-a-Ride', 40.933, -74.425, 2 ], ['Butler Borough', '835-8885', 'Dial-a-Ride', 40.999497, -74.346326, 3 ] //other locations and categories ]; var map = new google.maps.Map(document.getElementById('map'), { zoom: 10, center: new google.maps.LatLng(40.7967667, -74.4815438), mapTypeId: google.maps.MapTypeId.ROADMAP }); var infowindow = new google.maps.InfoWindow(); var marker, i; for (i = 0; i &lt; locations.length; i++) { marker = new google.maps.Marker({ position: new google.maps.LatLng(locations[i][3], locations[i][4]), map: map, icon: 'http://labs.google.com/ridefinder/images/mm_20_red.png' }); markers.push(marker); google.maps.event.addListener(marker, 'click', (function(marker, i) { return function() { infowindow.setContent(locations[i][0] + "&lt;br /&gt;"+locations[i][2]+"&lt;br /&gt;"+locations[i][1]); infowindow.open(map, marker); } })(marker, i)); } // shows all markers of a particular category, // and ensures the checkbox is checked function show(category) { for (var i=0; i&lt;locations.length; i++) { if (locations[i][2] == category) { markers[i].setVisible(true); } } } // hides all markers of a particular category, // and ensures the checkbox is cleared function hide(category) { for (var i=0; i&lt;locations.length; i++) { if (locations[i][2] == category) { markers[i].setVisible(false); } } } // == show or hide the categories initially == hide("Dial-a-Ride"); hide("American Legion"); hide("Veterans of Foreign Wars"); hide("Nutrition"); $(".checkbox").click(function(){ var cat = $(this).attr("value"); // If checked if ($(this).is(":checked")) { show(cat); } else { hide(cat); } }); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
