You can quickly define column schemas on the go and create filters with a simple addition or deletion of conditions or groups, providing you with maximum flexibility and control. Furthermore, the component supports model binding, allowing you to bind properties to the components used in field and operator columns.

You can also organize hierarchical or multilevel data using subfields, ensuring a comprehensive and organized filtering experience. Customization options abound with the Blazor Query Builder. You can customize the UI using templates, adding controls like Checkbox, Slider, and Dropdown List to the header, columns, and value elements. Additionally, you can change the appearance of the component with custom styling and built-in themes, ensuring that it seamlessly integrates with your application’s design.
