Leaflet: Create layers from geojson "properties"? - leaflet

Question

I've new to mapping, and I've started creating my map following the documentations and tutorials on http://leafletjs.com. So far so good, I've manage to create a map, add a lot of geosjon data from geojson.io that dislay "popupContent" in a popup. And it works.
But I can't understand how create a few layers to sort all those markers. What I want is too use the "properties" to do it. I have properties named "status" with a values "done", "new" and "active".
Like so:
"type": "Feature",
"properties": {
"popupContent": "content",
"marker-color": "#FFFFFF",
"title": "title of project",
"status": "active
Is that possible? To create a 3 layers based on "status" properties?
If you need the html file to look at, say so and I can add it.
Thanks

You can use the filter option of L.geoJson to create separate layers based on the feature properties. Just specify a function that will return true for the features you want included in each layer:
var activeLayer = L.geoJson(yourGeoJson, {
filter: function(feature, layer) {
return (feature.properties.status === "active");
}
}).addTo(map);
var newLayer = L.geoJson(yourGeoJson, {
filter: function(feature, layer) {
return (feature.properties.status === "new");
}
}).addTo(map);
var doneLayer = L.geoJson(yourGeoJson, {
filter: function(feature, layer) {
return (feature.properties.status === "done");
}
}).addTo(map);
