Sub-form is suitable for scenarios where relationship data is created first and then associated. Multi-level relationship data is clearly displayed through nested form format. Unlike data picker and dropdown selector, sub-form can directly maintain relationship table fields in blocks on the current page, and relationship data is submitted together with the main table.
Supports nested display of multi-level relationship fields, such as products and parts.

After enabling this function, users can add multiple records by clicking the "+" sign.

Supports switching to other relationship Field Components, such as dropdown select, data picker, etc.
