Welcome, but please attach a workbook for faster help.
I think I understand what you are asking. So you have a web form you are collecting responses with, correct? Possible answers to a response would be Yes, No or Unanswered (Null).
Once you have collected responses and connect your data to Tableau. You should see column that the responses exist in as a Dimension (Blue Pill). You should be able to then, bring that blue pill to the columns shelf.You should also see "Number of Records" under Measures. Bring that Green Pill to the rows shelf. That will give you a basic visualization for quantities per response type. I hope points you in the right direction!
Thank you for the feedback, Eric. Knowing a little more than I did when I posted, I think I can rephrase a little more clearly.
We are looking for a way to essentially build a user form in Tableau, allowing the users, within the program, to check boxes. The results then would flow back into the data or be presented on the dashboard.
My boss isn't even sure this can be done. So my goal is to find out if this is possible, and then build it if I can.
Ok, I think I understand. Can this be done easily? No.
You will save yourself a headache creating something for your users to fill out with Google Forms/Google sheets (or other service), taking that data and creating views/dashboard in tableau.
I have seen a example of someone doing something similar to what you are hoping for here, The Don Data: Data Entry / Write Back in Tableau using Google Forms and Google Sheets
