Category-specific fields

When you assign a category, additional fields appear tailored to that item type (e.g., Artist, Period, Mint Mark). These support text, textarea, number, dropdown, boolean, and date inputs. They appear in a dedicated section on the detail page and support quick edit.

Subcategory fields (Premium) provide a second level of specialized attributes, visually grouped beneath the main category fields.

If no category is assigned, only standard fields are available. You can add or change the category at any time.
