Custom Fields - replaysMike/Binner GitHub Wiki
You can create your own custom fields for certain data types. Currently Binner supports extending Inventory (parts), BOM Projects and Users.
To create a custom field, visit the Settings => Custom Fields section.
When you add a custom field, they will appear on the corresponding Inventory, BOM and Users pages where you can populate data for each item.
Currently, the import/export tools don't support custom fields but we plan support that shortly.
