This problem occurs because both labels have the same zIndex in this situation, 
a zindex which is 1 higher than the zindex shared by the markers. This means 
the two labels appear above BOTH markers, causing visual confusion. The 
solution would involve putting the label's div inside the corresponding marker 
div but this is not possible because Google does not provide an API to return 
the marker div.

I don't have a good workaround for you at present. An easy fix would be 
possible if Google provided a method for returning the div used for placing the 
marker on the map.

Is there any news to this issue? Or has anyone figured out a workaround for it?

No easy workaround identified. If Google were to provide a method for returning 
the DIV of the parent marker, the problem could very likely be fixed.

Has a request about a method to return the marker div been filed in 
gmaps-api-issues? ( http://code.google.com/p/gmaps-api-issues/ )

I have looked around there but haven't found anything about this, Maybe a good 
idea would be to file a request?

This issue cannot be resolved without an API change from Google.

i was thinking in using the zindex and the labelzindex and give values based on 
it up and left positions

ive tested with random values and it seems to work, but i can´t reach the  
exacly formula that would make it possible

any ideas?

Original comment by erikrpi...@gmail.com on 20 Apr 2013 at 9:48

[GoogleCodeExporter]

I have looked at this long and hard and I believe the only solution is as 
indicated in #1 above. i.e., an API change is required so that access to the 
DIV containing the marker.

ok thanks, i´m gonna look around to see if there is an alternative to 
markerwithlabel

As a possible fix you could try setting a z-index and background colour to your 
marker labels. You'll have to set the width of the marker label to match the 
marker itself but gmaps scales it really nicely.

Works well for me.

Sample Workaround
//off function
var hoverOffset = 80000;

//Marker creation function
          var latLng = new google.maps.LatLng(property.lat, property.lng);
          var newStyle = MAPS_MARKER_LABEL_STYLE;
          newStyle['z-index'] = hoverOffset + 1;
          var marker = new MarkerWithLabel({
            cursor: 'pointer',
            icon: MAPS_SINGLE_CLUSTER_IMAGE,
            id: property.id,
            map: map,
            position: latLng,
            labelContent: 'blahblah',
            labelAnchor: new google.maps.Point(6, 30),
            labelStyle: newStyle
          });
          marker.setZIndex(hoverOffset);
          hoverOffset += 2;
          markers.push(marker);

Confirming that the solution in #19 seems to work! I did have to tweak the 
formatting to:

var newStyle = hoverOffset + 1;

var marker = new MarkerWithLabel({
labelStyle: {zIndex:newStyle}
});

I think #19 and #20 doesn't work.
I modified the fiddle from Issue 271: http://jsfiddle.net/waldert/5zxqo3fs/

Any Idea? As is see the google ticket is closed...

I encountered this issue recently. The work around we used was to set the 
marker pin in the CSS via labelStyle, this is then applied at the same z-index 
as the labelContent. Obviously not a perfect solution but workable, especially 
with the support of CSS background-size.

I got the same issue. It's really terrible if you have 15 markers close to each 
other. All labels are on the top, even if I give them a different z-index via 
the loop that creates them.

I was able to work around this issue with the hint of #22.
My marker image is now the background-image of the label class. To fool Google 
Maps to not use the default marker icon additionally, I used a 1x1 transparent 
image as the marker-icon.

#24 works great! Thanks!

#22 #24 works but can't use animation on the marker now to show current marker 
:(

Original comment by nikreati...@gmail.com on 7 Jan 2015 at 5:02

[GoogleCodeExporter]

#26 why not? You should be able to use any CSS animation on the "label"-classed 
element.

Original comment by SumitStu...@gmail.com on 7 Jan 2015 at 5:10

[GoogleCodeExporter]

I found only one solution: (version 1.10)
instead of 
line 141:
this.getPanes().overlayImage.appendChild(this.labelDiv_);
use this:
this.getPanes().markerLayer.appendChild(this.labelDiv_);

The overlayImage pane is pane which every elements overlay the any element of 
image and marker layer.

Because z-index work only in theier stack context, so any change of z-index 
can't solve this problem. Onle when you add the label and marker image to same 
pane, you can work with z-index.

Currently it's work for me.

I had to combine #19 with #28.. Works now

#28 worked for me as well, and should be included in the official release 
version

I confirm #28 works.
I tried using the newest version, modifying the same code at line 77 but labels 
weren't showing.
Version 1.1.10 works perfectly as mentioned.

#28 works. Is it possible to add this to the normal release?

Original comment by tzaferis...@gmail.com on 27 May 2015 at 10:47

[GoogleCodeExporter]

I tried both #28 and #19, also together but they dont work.. What did you do 
exactly?
I downloaded the newest version, 1.1.10, changed line 141 from
this.getPanes().overlayImage.appendChild(this.labelDiv_);
to
this.getPanes().markerLayer.appendChild(this.labelDiv_);
but nothing changes. I also added an incremental 'z-index' inside the 
labelStyle but its the same as before..

I'm with #36, this (#28) doesn't seem to work for me. I am still seeing the 
labels overlap.

I downloaded the newest version, 1.1.10, changed line 141 from
this.getPanes().overlayImage.appendChild(this.labelDiv_);
to
this.getPanes().markerLayer.appendChild(this.labelDiv_);

Also tried changing line 145 from:
this.getPanes().overlayImage.appendChild(this.crossDiv_);
to
this.getPanes().markerLayer.appendChild(this.crossDiv_);

Neither fixed the issue. 

I am creating the marker as such:

var marker = new MarkerWithLabel({
                position: new google.maps.LatLng(geoLocation[1],geoLocation[0]),
                title: title,
                id: _id,
                icon: "files/pins/default.png",  
                labelContent: icon.svg,
                labelAnchor: new google.maps.Point(11, 53),
                labelClass: "map-svg-icon",                
            });

One way of getting around this is to use MarkerClustererPlus.

Since this issue is 5 years old and no code was commited to this project for a 
year I commited #28 to a fork on github at 
http://github.com/cdaguerre/gmaps-utility-library and registered it on bower as 
gmaps-utility-library
