I want to add additional option to the subcategory attribute but I cannot locate where to update its content within the Magento Admin Panel.
See this link for full image - https://drive.google.com/open?id=16sFqr_i_9jRyAs4yDTwAVPeDIkfAz0Il
Currently, I have no access to the backend/module files, so I am not sure if its hardcoded or can be edited within the admin panel.
Please help. I am very new to Magento.
