Hi,
thanks for the detailed reply. I will try to answer why we were considering these options.
1) But first: Our username seems to be an email address. Could this be changed to a normal username to avoid spam?
a) With posting the forum post I submitted some data and also a link to one prototype book product. In case you want to have the look.
Indeed you are right: The main reason not going for the 20 variants was that the selection will be very long. So drop down did not seem good and a long list also did not seem very nice. The product description is the table of contents of the book and it is quite long, so if the variants list is long as well it looks kind of strange.
The idea was indeed, as you say, to send the PDF by email individually, also, because we are not expecting many sales. I would be 1-3 chapters per year or so. This is academic material, so the reason why it is online, is not profit, we are non-profit organisation, but rather scientific interest. So we wanted to keep things as simple as possible.
BTW, for automatic PDF downloads is there some option for PDF branding? Because if we send it by email, we could easily at least add the name of the person to each page of the pdf. It's not super secure of course, but ok, better than nothing.
For the variant solution, I would not really now where to put the list of options, top, bottom, .... Maybe I can code something to have the custom text field disappearing, or do something with ReReplacer or so.
What do you think?
Regards
Philipp
