Information needed to dynamically add markers

Bonjour,
First of all thank you for this plugin.
I have issues adding dynamically some markers to my map.

First try : Using mapfeaturesids. I uploaded some tiles to mapbox and put the id in this attribut.

[mapboxadv_map mapid="1"]

This didn’t work, my markers wouldn’t be displayed on the map.

2nd try : Using mapfeaturescode. I didn’t understand your sentence

A GeoJSON object, from your own Javascript code.

I just put my Javascript between <script> just before the shortcode.

<script type="text/javascript">

var test = [
  {
    "type": "Feature",
    "geometry": {
      "type": "Point",
      "coordinates": [2.35,48.85]
    },
    "properties": {
      "icon": {
         // icon properties ...
      }
    }
  }
];
</script>
[mapboxadv_map mapid="1" mapfeaturescode="test"]

This didn’t work either.

3e try : Same as 2nd but putting the whole JSON Object in the attribute entirely.

[mapboxadv_map mapid="1" mapfeaturescode="{\"type\": \"FeatureCollection\",\"features\": [{\"type\": \"Feature\",\"geometry\": {\"type\":\"Point\",\"coordinates\":[2.35,48.85] }, \"properties\":{}}]}"]

Here the ] closes the shortcode at the wrong end.

Sorry for this long post, and thank for your help.
