# Elements

***

The Felt SDK lets you read, create and update elements on the map.

Elements that are created via the SDK are only available to the current\
session - they are not persisted to the map and not available to other users\
of the map.

> If you want to let your users create elements (as opposed to using the SDK to\
> create them programmatically), you can use the [ToolsController](https://developers.felt.com/js-sdk-api-reference/tools/toolscontroller) to\
> select and configure the drawing tools in Felt.
