When you click the 'change' icon to edit the machine, project name or release, the transition to the editable state should use a slide down a animation. When, in the editable state, you click Save or Cancel, the transition to the not editable state should use a slide up animation. The animations have been already implemented in the layer details page for imported layers. You can have a look at them there.
I am withdrawing this case because the project page has been redesigned to not use Angular, hence the premise of this case no longer applies.
