Webform as a block only When I crate a Webform I do have an option to make it available as a block as well. But in this case it creates a node as well.
How can I create a Webform as a block only?
You will need to create a webform as node. Edit the node and navigate to:

Webform tab -> Form Settings tab -> Advance Settings (located at the bottom of the page).
Check the checkbox for Available as block and your webform will be a block.
