[Prashant Kumar]

I have 4 json files with coordinates. I want to show marker on map with checkbox selection. My issue is when I click on checkbox the marker is appear but when I uncheck the checkbox the marker is not disappear. 

Here's my code : http://codepen.io/prashantkrsahu/pen/ZbZdvq

Hi Prashant,

one approach to make the markers disappear when uncheck the checkbox is to make them unvisible with  'setVisible(false)'.

To get all the markers of a category you need to put them in an array and go through all markers to make them invisible:

      for (var i=0; i<gmarkers.length; i++) {

          if (gmarkers[i].mycategory == category) {

            gmarkers[i].setVisible(false);

          }

        }

Have a look to the whole example here: http://www.ralf-wessels.de/test/apiv3/marker_categories.html
