Purpose:  Populating fixed field positions is difficult and likely requires consulting additional resources to ensure the right codes are used. Adding dropdowns with available codes for each position supports both efficiency as well as accurate data entry. For the positions that can be edited, we need to add a dropdown for each. This dropdown is consistent with the implementation for the 006/007 "Type" field, and will contain the valid values for that position. 

Requirements

• For the editable positions of the LDR, there needs to be a dropdown box containing the valid values for that position 

  • See the linked wiki page for the available values for each position

• If a record that is created via Data import contains a value that is not valid for the position, allow the record to be opened in quickMARC, but do not allow save and add error toast message that says: "Record cannot be saved. Leader contains invalid values."
