# Themes Each theme corresponds to an inventory sold by Jakarto. If your organization has purchased a [municipal asset inventory](https://www.jakarto.com/en/products), the associated theme will be available when you are logged in with your Jakarto account linked to your organization. ### Selection of layers to display For each theme, individual assets can be selected by checking the corresponding layers.

You can select all layers within a theme by clicking the **"Select All"** button.

### Statistics The numbers displayed to the right of the layer names indicate the count of objects within the current view. You can obtain the object count within a restricted area by [drawing the perimeter](https://docs.jakarto.com/asset-viewer/en/tools#drawing-geometries). Some counts represent either the total linear meters (m) for linear objects or the sum of areas in square meters (m²) for polygonal objects.
