I have a view (block) created. When I modify the view block, I have only the field "block title" in the form. However they are 3 fields (block title, block description et block body) in a block of drupal (which I can create via /structure/block/add).
So my question is how can I add a custom field (like a textfield) to the form of views block? Is it possible to add it programmatically?
Thanks in advance.
