I have 3 Product Series (Taxonomy) I am trying to change what the Product Form looks like based on the Product Series, so if it is "SheauPac" it would show a radio button on the Product Form.
Is there any documentation that you are following?
No
Is there a similar example that we can see?
I do not think so
You want to conditionally display an input in a form based on the selection of a taxonomy field on the same form?
You can do that, but the GUI doesn't let you insert conditions for taxonomies directly, you have to add the condition manually.
So, add a Conditional Group to your form (you can drag it from Extra elements in the sidebar), and expand it to be able to add a condition.
Click the link to edit the condition manually, and then add the condition in this format, where in my example the taxonomy slug is "colour" and the term I'm testing to see if it is checked is "Red":
($colour) eq 'Red'
Drag whatever field you want to conditionally display inside the Conditional Group block. In the screenshot in my example I'm simply adding an HTML block with some text, but you can add your radio input there.
