I have read the tutorial 'Modifying Post Template' in the Upfront Builder documentation, but there is no description in HOW to do the modifications described.
I started from scratch with a new theme (Bergen Hjemmekennel). I used the Custom Content plugin to create a custom post type 'Vertsfamilie' - and now I am trying to create a post template for that type. I did the 'Select a New Layout to Create', and selected 'Single Vertsfamilie'. I added the global sections for header and footer, and now I am ready to add the 'Featured image'.
Using the toolbox I did find the elements for 'Date posted', 'Title' and 'Content' - but no 'Featured image'..
I did find the 'Featured Image' in the 'Data' section of the 'Draggable Elements' but there was no way to drag this into the post section - only to a separate section..
So now I need a more detailed 'howto' for bringing this further..
