I am using SPDesigner to create a custom page layout.
I create a page using Design Manager within O356, and then edit the page generated. I have managed to get custom webpart zones in. However I am having issues with Summary Links.
I would like to have 4 zones with Summary Links. The default page comes with one summary links, and it works fine. When I create another one (using the Snippet Generator) and I place the given code in my custom page layout, I get to see it correctly in the page layout preview mode.
After Check-in and publishing a major version of the page layout, when I go to edit the page with my assigned page layout, the summary links zone is (a) empty, (b) not editable.
