Layers and Initial Visibility

[Arnie Shore]

All,I have a number of overlay layers in my application, and these
show up fine. But now I'd like some of these not to be shown in the
initial map load, but then made visible by using the standard layer
control (I.e., those layers unchecked as the default.)

(Please be gentle; it's not my first time, but I'm still new at this.
(;-}) Thanks, all.

To clarify: In the tutorial at
http://leafletjs.com/examples/layers-control.html, how wd I set, say,
Cities, not to show on page load, but Motorways to do so. AS

Hi Arnie,

You're not the first to struggle with this;) Fortunately, the solution is easy- simply add the layer to the layer control, but NOT the map layer array.

var map = L.map('map', {

    center: [39.73, -104.99],

    zoom: 10,

    layers: [minimal, motorways]

});

var baseLayers = {

    "Minimal": minimal,

    "Night View": midnight

};

var overlays = {

    "Motorways": motorways,

    "Cities": cities

};

L.control.layers(baseLayers, overlays).addTo(map);

Hi Bryan,
o.k., but then the order of the overlays is changed -> first all on's then all off's (logical...). Is there a way to keep the original order as they would be all on?
In my example: Wanderungen Band 1 - Band 2 - Band 3 - Band 4 - Band5?

keep order_overlay

thxalot...Michelinho

Try adding them initially and then immediately removing them to preserve the layer order:

var map = L.map('map', {

center: [49.36807, 7.0697],

zoom: 8,

zoomControl: false,

layers: [landscape, iconsBd1, iconsBd2, iconsBd3, iconsBd4, iconsBd5]

});

map.removeLayer(iconsBd2).removeLayer(iconsBd4);
