Hey JC,
See this thread where the issue is discussed: https://www.wix.com/code/home/forum/questions-answers/tab-to-next-field-in-user-inputs
Here’s Sam’s solution from the thread, which seems to work, but look at the thread because it seems some people needed to tweak it a bit: “You can set the order by right-clicking and selecting Arrange > Bring to Front in the order you want users to tab through your form.”
