      Hello there, 

      In the form builder,
      Add two select boxes: selectBox1 (single select) and selectBox2 (multi-select).

      Add a Custom HTML and, add this script:


      <script type="text/javascript">
          $(document).ready(function() {
              // Function to update options in the second select box
              function updateSelectBox2() {
                  var selectedValue = $('#selectBox1').val();
                  $('#selectBox2 option').show(); // Show all options initially
                  $('#selectBox2 option').each(function() {
                      if ($(this).val() === selectedValue) {
                          $(this).hide(); // Hide the selected value from selectBox1
                      }
                  });
              }

              // Event listener for changes in the first select box
              $('#selectBox1').change(function() {
                  updateSelectBox2();
              });

              // Initial call to update selectBox2 on page load
              updateSelectBox2();
          });
      </script>

      Make sure #selectBox1 and #selectBox2 match your select box IDs. This script hides the selected value in selectBox1 from selectBox2, avoiding repeated values.
      Adjust the code accordingly based your field ID 

      Hope this helps!
