# Managing layers in a project

The layers of a project are displayed in the **Layers** section, which may be accessed from the JMap Admin project configuration interface. In the **List** tab, the table shows basic information about each layer of the project. When you click on the name of a layer, a details section displays. The **Hierarchy** tab displays the groups and subgroups with the layers that compose them. The tasks you can perform from this tab are detailed in the [Organizing Layers](https://docs.k2geospatial.com/en2/administrator/jmap-server-administrator-manual/projects/configuring-projects/organizing-layers) section.

In the **List** tab of the **Layers** section of a project, you can perform the tasks described in the table. For some tasks, you must select more than one layer.

## Bulk editing a layer set

You can edit different settings for a set of layers. You must select the layers to modify in the **List** tab of the **Layers** section of the project. Afterwards, press the **Update** button, and click on the **Bulk edit…** option. The **Bulk edit** interface will open.
