I have one dropdown outside the multifield with 2 option With Image and without image

if I select with Image in dropdown Multifield should come up with Text area and Image If I select without Image Multifield should come up with only Text Area

Using AEM Showhide it is not working. Please guide me with custom JS to solve this issue

NOTE- Cannot use 2 multifield as we have used Min and Max item in multifield which is min-2 and max-8.
