title: How to make a step-by-step choice?
body: <p>There is a task. It is necessary to give the user a choice in the first step between 3 (input radio). After he chose one of the items he needed, a second column appears with the new column (input radio). And also after the choice in the second step appears the third step with the final choice (input radio).</p>
  
  <p>It is important that the second step and the third for each selected item are new.</p>
  
  <p>Help solve this problem.</p>
  
  <p>I found a similar task, but it's a little unsuitable for my purposes.
