Using input[checkbox] for selecting numbers
I'm experimenting with something and I would like your opinion.
Trying to build an email with several inputs where the recipient can choose some numbers, and if so send some king of data to an external page where the parameters / attributes can be read from some script and understand which numbers were selected.
Here's a preview:
[ obviously this will have very limited support, still taking the long shot :) ]
Can we limit somehow how many of these inputs can be selected / clicked? For example when 4 of those are "selected", no more of those can be.
Is it possible to and how could I append those numbers to a url, like https://superemail.com/?n1=5&n2=9&n3=10
Thank you very much in advance
