# Element Exists Block

Check the document to see if an element exists.

If there is an element, the workflow will run the block that connects with the first output. Otherwise, it will run the `fallback` output.

* **Element selector**
* **Try for**\
  Set how often to check the element according to the selector.
* **Timeout**\
  By default, the delay is 500ms.
* **Fallback**\
  A fallback when the element is not present.
* **Throw an error if doesn't exist**\
  Initiate an error rather than perform the fallback.
