I am using a lightning:recordEditForm to show some fields on UI. In that there are lookup of Account , contact and opportunity which i am populating using some backend logic using fieldsets. How can i provide a "New Contact" option when a user clicks on the Contact lookup? This option shows in standard lookups, is it possible in this scenario as well?
Also, is it possible that i can control the search suggestions which user will get on clicking on a particular lookup? Like on clicking of Opportunity lookup , Only those opportunities should be shown in suggestion which has stagename not equals to closed won
