I am taking over for a outsourced team that I have no contact with. I want to replicate something that they have already done but I cannot figure out how they did it. I want to take an existing VF page and insert it into a subsection of an Account Page. The 'associated contacts' section of the picture is the custom VF page that the other team embedded. I want to do this in another section below it. Any help on where to start? I have looked into the 'edit layout' and 'customize page' buttons but there doesn't seem to be a way to import a new VF page. See attached picture.
Make sure that page, that you want to add is using standartController of you object:
<apex:page standardController="Opportunity" id="pg"> or <apex:page standardController="Account" extensions="yourCustomExtension">
Then go layout -> edit -> visualforce section -> add where you want -> save:
HOC is name of mine page
