How do I create parameters in a Joomla module depending on another parameter / number?

Question

I'm trying to create a Joomla module for typical CSS cards, but I want to make the number of cards dependent on a number input from the user. For example the user wants 5 cards so in the parameter field "number of cards" he puts '5'.

Now he has to choose the text and logo for each card he wants, but how can I 'spawn' parameter values during runtime?

I could just put a set number of cards in and define the corresponding parameters in the modules XML, but is there a way to do it like I want to?

I can't say exactly how to make your question, but I used something similar to show a field conditioned to the value of another field in the 'showon' attribute with XML Path Language (XPath). I believe it is something similar. You can find out more at the link:
