I have a vf page being displayed on a detail page of a custom object.So is it possible to display the vf page in a hover manner like related list hover?
Unfortunately, no it's not possible to inject your Visualforce page into the hover links on the page layout. You could create a custom link on the page layout and link it to your VF page, but it wouldn't reside in the same spot as the hover links.
