I was hoping one of you could help me with an issue I am having. I have to add a footer web part zone to dispform.aspx on a list in SharePoint 2013. Our SharePoint 2013 platform is heavily customized, and currently dispform.aspx has 2 columns, a left web part zone and a right web part zone. My attempts in adding this footer (via SharePoint Designer) have resulted in breaking the form forcing me to reset it to the site definition. I have tried googling this question, but it doesn't seem a popular topic.
Alternatively if you wont do a lot of custom things : 1. You could edit the dispform page by getting its url 2. Add a content editor webpart below with your custom html
Let me know how you figured out
I would suggest completely changing the Dispform.aspx for the specific list (or content type altogether) with a custom page. You can add your extra WebPartZone in there.
