# Element Types

Element types are just content types, but they are exclusively used in the [Block List Editor](broken://pages/p59JGkBArBvWkCb1zZkz) and you cannot create content in the content section from an element type ONLY a content type.

You can switch an element type back to a full content type by just toggling the Is Element Type button. However we wouldn't recommend this unless you are sure your element type is not being used.

### Preview Image

Because element types are used in the [Block List Editor](broken://pages/p59JGkBArBvWkCb1zZkz) you can also add a preview image for an element type. Doing this creates a much better UX for the editor, as you can custom make images theat represent the type of content 'Block' you are adding. The image below shows an example of what the block picker in the Block List editor looks like when you add custom preview images.
