Hover over show of Leaflet Marker from control panel

I have a map with different markers. The markers could be selected from the control panel. But, I would like to show the preview of the markers, when we hover over the marker tab in control panel.
If possilbe, the hover effect similar to the following jQuery example
Can anyone help me how this could be acheived? Following is the code:
// Map intialization
var map = L.map('map').setView([51.505, -0.09], 12.5);
// OSM layer
var OSM = L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
attribution: '© OpenStreetMap contributors'
}).addTo(map);
// OSM HOT
var OpenStreetMap_HOT = L.tileLayer('https://{s}.tile.openstreetmap.fr/hot/{z}/{x}/{y}.png', {
maxZoom: 19,
attribution: '© OpenStreetMap contributors, Tiles style by Humanitarian OpenStreetMap Team hosted by OpenStreetMap France'
});
var singleMarker = L.marker([51.505, -0.09]);
// Layer controller
var baseMaps = {
"OpenStreetMap": OSM,
"OSM HOT": OpenStreetMap_HOT
};
var overlayMaps = {
"Marker": singleMarker
};
var layerControl = L.control.layers(baseMaps, overlayMaps, {
collapsed: false,}).addTo(map);
JSFiddle Example

Can you something like grabbing the event of the marker? Like so:
$('.leaflet-pane.leaflet-marker-pane').hover(function(){
alert('your code here?');
});
And from there call the tooltip event to show next to the marker?

Leafletjs show my location marker instead of hardcoded location

I am trying out Leaflet.js and I have a map with a marker like this:
var marker = new L.marker([5.897818, -1.120009],{
draggable: true,
autoPan: true
}).addTo(mymap);
This is showing ok but I want it to appear on my current location instead of the above hardcoded location.
How do I do this?

What you need is to tap into the Geolocation API and use the results of that to create a marker.
var mymap = L.map('mapid').setView([51.505, -0.09], 13);
navigator.geolocation.getCurrentPosition(position => {
const { coords: { latitude, longitude }} = position;
var marker = new L.marker([latitude, longitude], {
draggable: true,
autoPan: true
}).addTo(mymap);
console.log(marker);
})
There's some issue issue using the API with Stackoverflow, so here's a link to a working JSFiddle.

Setting multiple toggleable KML layers on GoogleMaps with custom icons

I would like to create a Google map with toggleable KML layers - every layer has its set of icons. Example of a map I would like to use can be seen here.
I am unable to set separate layers on the map so I can continue with making them toggleable one by one.
These are my steps for obtaining data for KML layers on Google map:
1. Select "Download KML"
2. I chose a layer ("Food stores" for example)
- I checked "Keep data up to date with network link KML" (Map will be maintained on Google maps and data should automatically refresh in my map on the website).
- I left unchecked "Export to a KML file" (because of the icons support)
Then I unzip downloaded files. Inside small code there is <href>http://www.google.com/maps/d/kml?mid=16i6f7Jvm754_jzkltP-Ks_2pKbU&lid=M97Oy53L0t4</href> which I include in url of sitesLayer when passing data for function loadKml() at the bottom of the following code.
The problem with this is that I instantly get all those icons on the map, even if I have downloaded and included only 1 layer - the map shows all 4 of them.
Am I missing something, in the code or in the steps for downloading KML files for separating layers/icons?
function initialize() {
// Map settings
var myLatlng = new google.maps.LatLng(0,0);
var mapOptions = {
zoom: 18,
center: myLatlng
};
var map = new google.maps.Map(document.getElementById('map'), mapOptions);
// Creating KML layers
loadKml = function(opts,map){
var layer = new google.maps.KmlLayer();
opts.preserveViewport = true;
if(map) {
opts.map = map;
}
google.maps.event.addListener(layer,'defaultviewport_changed',function() {
var map=this.getMap(),
bounds=map.get('kmlBounds') || this.getDefaultViewport();
bounds.union(this.getDefaultViewport());
map.set('kmlBounds',bounds);
map.fitBounds(bounds);
});
layer.setOptions(opts);
return layer;
}
// Setting KML layers
var sitesLayer = loadKml({
url: 'http://www.google.com/maps/d/kml?mid=1AQ5Is7NjBGjPZpLji5fbApYnegk&lid=z-AEWAAfH9c',
map: map
});
var sitesLayer2 = loadKml({
url: 'http://www.google.com/maps/d/kml?mid=16i6f7Jvm754_jzkltP-Ks_2pKbU&lid=jY6tGqHtk80',
map: map
});
}
google.maps.event.addDomListener(window, 'load', initialize);

Load markers before map

I'm trying to reproduce Foursquare's web user interface.
What I noticed is that on the tip map, the markers are load way before the map was loaded.
is this possible with leaflet ?
With this piece of code, I don't think it's possible
L.marker([lat, lng], {icon: iconMarker}).addTo(map);
How are they doing it?

I think I know how:
They're loading the Tiles after positioning the markers, something like :
markers = L.marker([lat, lng], {icon: iconMarker}).addTo(map);
L.tileLayer('https://{s}.tiles.mapbox.com/v4/MapID/{z}/{x}/{y}.png?access_token=Token').addTo(map);

Ofcourse, just as long as the Leaflet library is loaded, you can create markers, layers, polygons, whatever. There doesn't have to be an instance of L.Map to do this.
// Define marker first
var marker = L.marker([0,0]);
// Define map later
var map = L.map('map', {
'center': [0, 0],
'zoom': 1,
'layers': [
L.tileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
'attribution': 'Map data © OpenStreetMap contributors'
})
]
});
// Add afterwards
marker.addTo(map);
Working example on Plunker: http://plnkr.co/edit/0zaogf?p=preview
Or include the marker when defining the map:
// Define marker first
var marker = L.marker([0,0]);
// Define map later include marker
var map = L.map('map', {
'center': [0, 0],
'zoom': 1,
'layers': [
L.tileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
'attribution': 'Map data © OpenStreetMap contributors'
}),
marker
]
});

map as div background - Google Maps API

I'm using for a while following javascript code to load google map as DIV background.
// When the window has finished loading create our google map below
google.maps.event.addDomListener(window, 'load', init);
function init() {
// Basic options for a simple Google Map
// For more options see: https://developers.google.com/maps/documentation/javascript/reference#MapOptions
var mapOptions = {
// How zoomed in you want the map to start at (always required)
zoom: 15,
// The latitude and longitude to center the map (always required)
center: new google.maps.LatLng(54.549047, 18.443433), // New York
// How you would like to style the map.
// This is where you would paste any style found on Snazzy Maps.
styles: [ { featureType:"all", elementType:"all", stylers:[ { invert_lightness:true }, { saturation:10 }, { lightness:30 }, { gamma:0.5 }, { hue:"#1C705B" } ] } ]
};
// Get the HTML DOM element that will contain your map
// We are using a div with id="map" seen below in the <body>
var mapElement = document.getElementById('map');
// Create the Google Map using out element and options defined above
var map = new google.maps.Map(mapElement, mapOptions);
}
works perfectly. But when I've tried to load there a marker which will point to my location, it crashes. Any ideas what will be the proper placement of such? I assume this is the proper code (which doesn't work..):
var myLatlng = new google.maps.LatLng(54.549047, 18.443433);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: 'Hello World!'
});
thanks for the help!
