Suspending Props in the air?

Hey, i've seen a few videos of props being 'stuck' in mid air and would like to try and replicate.

Any idea how to do this? all props drop automatically and from what i can see i cannot see a option to deal with gravity or weight (while in edit map mode (F11))

i.e I'm trying to add props to the 'ramp map' to make things a bit more challenging; like hoops to aim through etc, like the video below



Many thanks.

or if you have a hoop mod nodegrabber

 

When i'm in world editor (F11) any prop i spawn falls to the ground, is there a certain setting/option i need to check/uncheck?

 

use the nodegrabber

 

Had a blonde moment, many thanks!
