I can see that the normal way to add content to a DNN page is with a module.  But what do you do when there is no module that fits.  Suppose, for example, I want to let the visitor build a deli sandwich  and I want to show 10  images of condiments that they can click to add to their sandwich. And the result will go into a record in a table of  the database that represents this visitor's order. Is there a way to just add the necessary HTML/CSS somewhere, or do I have to build a custom module?

Thanks

Totally agree with Sebastian. Since your requirements are specific, you will need to develop a custom module or have someone develop it for you.

Hi Sebastian! Hope you're fine. Yes I do read the replies that others give, before I just type my suggestion. It's stupid when you just type exactly what ohers have typed. In this case I just clarified the reason why he needs a custom module developed. Meaning, it is not because there is a limitation in DotNetNuke or anything but because the requirement is specific :)
