I want to create a check box custom field that when checked opens up another custom field related to it e.g:

If i check RFA attached then a multi line input field should open up.

Thanks for any help

You can't do it out of the box. Being in the cloud you have limited options for plugins. If you have scripting you may be able to do it.
