Syncfusion Blazor Query Builder

If you need users to build complex filters with AND/OR logic and nested conditions, this is the Syncfusion Blazor component for that. It's designed for advanced search UIs, business rule engines, and anything where people need to construct queries visually without writing code. The docs cover the basics like defining columns and data types, plus more useful stuff like programmatic rule management, drag and drop, state persistence, and exporting queries to JSON or SQL. You get clone and lock operations for rules and groups, which is handy for workflow scenarios. It's a full featured component, so expect some learning curve, but the event system and data binding patterns are straightforward once you work through the initial setup.
