Empty container fileds

[madmax]

Trying to compile a list of "questions" (text field) and images (container field). I select the questions that I want to print out, however if the question does not have an image (ie an empty container), I do not want a blank container to appear on the printout. The "sliding" function works fine for the text field, but even though the container field for the image is empty it still prints a blank container ie it does not slide a container. How do I leave out empty container fields from my print out?
