!! `<$geomap>` widget
The `<$geomap>` widget displays an interactive map using [[Leaflet.js|https://leafletjs.com/]]. `<$geolayer>` and `<$geobaselayer>` widgets inside the `<$geomap>` widget are used to indicate the overlay layers and markers to display, and the base map layer to be used.
The following attributes are supported:
|!Attribute |!Description |
|''state'' |The title of a state tiddler used to track the state of the map in the `zoom`, `long` and `lat` fields |
|''startPosition'' |Optional starting position for the map: "world" (the default) shows the entire map, "bounds" zooms to the bounds of the loaded layes |
|''layersPanel'' |Optional starting status for the layers panel: "collapsed" (the default) causes the layers panel to initially be shown collapsed, "open" causes the layers panel to initially be shown opened |
If no base layers are defined by `<$geobaselayer>` widgets within the `<$geomap>` widget then all the available base layers will be loaded by the equivalent of the following code:
```
<$list filter="[all[tiddlers+shadows]tag[$:/tags/GeoBaseLayer]]">
<$geobaselayer title=<<currentTiddler>>/>
</$list>
```
