Filtering in React Query builder component

30 Jan 202311 minutes to read

Query Builder allows you to create or delete conditions and groups. You can use showButtons to enable/disable these buttons.

You can create or delete conditions by interacting through the user interface and methods.

• Use the addRules, and deleteRules methods to create/delete conditions.
• Use addGroups, and deleteGroups methods to create/delete groups.
