Hello,

In ClickUp, it is not possible to create a hierarchical dropdown custom field with a clear parent–child (main category–subcategory) structure.

Dropdown options cannot be linked hierarchically, meaning that selecting a main category does not trigger or restrict the available subcategory options. All options exist at the same level, which prevents proper category–subcategory modeling.

From an IT and data modeling perspective, the lack of hierarchical dropdown support makes structured data entry, standardization, and reporting difficult.

Thank you for your consideration.

Best regards,
