Conditionally Required Floating Items

How to create a conditionally required field in APEX (21.2):

• Create a Dynamic Action
  1. Event: Page Load
  2. Client-side Condition Type: Item = Value
  3. Item: P1_MY_REQUIRED_ITEM
  4. Value: Y

• Create a True Action: Execute JavaScript Code

let item = $("#MY_ITEM_TO_BE_REQUIRED");
item.prop("required",true);
item.closest(".t-Form-fieldContainer").addClass("is-required");
item.find(".t-Form-inputContainer”).prepend(");
