Reorder and group layers in a map¶
Overview of the Order and groups interface¶
You can reorder your layers and group some of them together.
Reordering layers can be handy, for example, if some of your layers are more important or requested than others. You can thus move the most important and/or requested layers at the very beginning of the list of layers so that they can be found more easily.
Grouping layers can also come in handy. For example, you might want to display different layers on your map, but they need to be displayed together to be really relevant. If you group these layers, you make them stick together: or they’re all displayed at the same time, or they’re all hidden.
Order and group management actions are made from the Order and groups interface. This interface is accessible from the Map Builder menu displayed at the very top of the map.

The interface of Order and Groups is composed of:
a Group button to group layers
a Split button to split groups
a switch button to see your map in Multilayer mode (several layers can be displayed at the same time) or in Monolayer mode (only one layer can be displayed on the map: choosing a layer automatically excludes the others)
the complete list of the layers of your map, with the following action buttons:
