# XWUIQueryBuilder

Nested rule groups for filtering a product catalog (or any field list). Emits a plain JSON `RuleGroup` on change. SQL/Prisma translation is the host's job.

Operators are type-specific. Value editors reuse `XWUIInputText`, `XWUIInputNumber`, `XWUIInputDatePicker`, `XWUIInputSelect`, and `XWUIInputSwitch`. Read-only mode renders the tree as removable chips.
