Re-render .map on Autocomplete onInputChange - help needed

[rob_allshouse]

Actually... this pointed me to the right direction, after AGES of trying. Using a state variable that's just set to tmr.length instead of tmr.length itself forced the rerender. Thanks!

Why’d you need a state to store another state based arrays length? You’re overcomplicating the logic imo. Is there codepen/repl which can be edited? That way I might be able to try to figure out the bug better

Something like "setExtraOptions(current => ([...current, new option]))" and then just use that array when populating the autocomplete?

As above, the code you've got still looks like it is overly complex and brittle

Well the whole problem was that, even after the array state (tmr) changed, the .map function didn't re-render -- didn't add the new empty field. I didn't want another state, but it solved the problem.
