FeatureGroup is stamped because it's passed as the context to layer.on in FeatureGroup.js:19.
Follow the steps given below to create a LayerGroup and add it to the map. Here how the code looks like for Adding Multiple Map Layers – Hide Show layer using leaflet js Before going through code in adding and hide – show multiple layer using leaflet, you should be having a good knowledge of adding point, line and polygon layer using leaflet js along with parsing geojson or topojson layer using leaflet js if you want to add topojson data layers. In both cases, the fundamental unit of showing/hiding is the group. Follow the steps given below to create a LayerGroup and add it to the map.

We recommend a zIndex value between 400 (the default overlay pane) and 500 (the default shadow pane). ordering. In each case, the omitted layer type will not appear for the user to select. I expect the order of the overlays to be as I supplied them, however, GeoJSON and FeatureGroup layers are moved up top. The Leaflet package includes functions to show and hide map layers. You can then use this pane to render overlays (points, lines, polygons) by setting the pane argument in leafletOptions.

leaflet () %>% addTiles () %>% addMarkers (data = coffee_shops, group = "Food & Drink") %>% addMarkers (data = restaurants, group = "Food & Drink") %>% addMarkers (data = restrooms, group = "Restrooms") Many layers can belong to same group. Using layer group, you can add multiple layers to a map and manage them as a single layer. This is because the FeatureGroup gets its _leaflet_id while it's created, while the other layers get it while they're added to Control.Layers. Flyers are great for promoting events, sales, product launches and more. map panes can be created by supplying a name and a zIndex to control layer How do you set the layer order in R's leaflet package so that tiles show up on top of polygons filled with color? FeatureGroup is stamped because it's passed as the context to layer.on in FeatureGroup.js:19.

Uses Leaflet's built-in layers control feature to allow users to choose one of several base layers, and to choose any number of overlay layers to view. A group is a label given to a set of layers. You assign layers to groups by using the group parameter when adding the layers to the map. autoZIndex This will give you control over the order of the layers, e.g. This tutorial shows only marker layers, but you could create icons for polygon layers and use those as well. The current leaflet implementation doesn't seem to allow setting the zIndex or pane properly (tiles and images are placed on the tile pane whereas polygons/lines/circles are placed on the overlay pane which has a higher zIndex). You can allow users to decide what layers to show and hide, or programmatically control the visibility of layers using In both cases, the fundamental unit of showing/hiding is the A group is a label given to a set of layers. If you call Finally, you can remove the layers in a group using If markers are addeded to different groups, and when using marker clustering as described in the Step 2 − Create a Layer object by passing the URL of the desired tile.

Option Type Default Description; collapsed: Boolean: true: If true, the control will be collapsed into an icon and expanded on mouse hover or touch. The Leaflet package includes functions to show and hide map layers. : autoZIndex: Boolean: true: If true, the control will assign zIndexes in increasing order to all of its layers so that the order is preserved when switching them on/off.

I expect the order of the overlays to be as I supplied them, however, GeoJSON and FeatureGroup layers are moved up top.
