@react-querybuilder/dnd

Augments react-querybuilder with drag-and-drop functionality.

To see this in action, check out the react-querybuilder demo with the drag-and-drop option enabled.

Installation

npm i react-querybuilder @react-querybuilder/dnd react-dnd react-dnd-html5-backend
# OR yarn add / pnpm add / bun add

Usage

To enable the drag-and-drop functionality of a query builder, nest the QueryBuilder element under QueryBuilderDnD. Pass in all exports from react-dnd and either react-dnd-html5-backend or react-dnd-touch-backend to the dnd prop of QueryBuilderDnD. (If you pass in all exports from both backends, the touch backend will be preferred when a touch device is detected.)

import { QueryBuilderDnD } from '@react-querybuilder/dnd';
import { useState } from 'react';
import * as ReactDnD from 'react-dnd';
import * as ReactDndBackend from 'react-dnd-html5-backend';
// OR
// import * as ReactDndBackend from 'react-dnd-touch-backend';
import { QueryBuilder, RuleGroupType } from 'react-querybuilder';

const fields = [
  { name: 'firstName', label: 'First Name' },
  { name: 'lastName', label: 'Last Name' },
];

const App = () => {
  const [query, setQuery] = useState<RuleGroupType>({ combinator: 'and', rules: [] });

  return (
    <QueryBuilderDnD dnd={{ ...ReactDnD, ...ReactDndBackend }}>
      <QueryBuilder fields={fields} defaultQuery={query} onQueryChange={setQuery} />
    </QueryBuilderDnD>
  );
};

Notes

• While not strictly necessary, we strongly recommend passing the react-dnd and react-dnd-html5-backend/react-dnd-touch-backend exports into QueryBuilderDnD. If they are not passed in as the dnd prop, the query builder will initially have drag-and-drop disabled until the dependencies are asynchronously loaded via import().

• QueryBuilderDnD will automatically set the enableDragAndDrop prop to true on any descendant QueryBuilder elements unless enableDragAndDrop is explicitly set to false on QueryBuilder.

• QueryBuilderDnD does not need to be an immediate ancestor to QueryBuilder, it only needs to be somewhere above QueryBuilder in the component hierarchy.

• Multiple QueryBuilders may be nested beneath a single QueryBuilderDnD. The same drag-and-drop settings will be applied to each query builder, and drag-and-drop will work across query builders (rules/groups can be dragged from one query builder and dropped into another).

• If your application already uses react-dnd outside the scope of a query builder, use QueryBuilderDndWithoutProvider instead of QueryBuilderDnD to inherit context from your existing DndProvider. Example:

  import { QueryBuilderDndWithoutProvider } from '@react-querybuilder/dnd';
  import { useState } from 'react';
  import * as ReactDnD from 'react-dnd';
  import * as ReactDndBackend from 'react-dnd-html5-backend';
  import { type Field, QueryBuilder, type RuleGroupType } from 'react-querybuilder';
  import { SomeOtherDndContextConsumer } from './SomeOtherDndContextConsumer';
  
  const fields: Field[] = [
    { name: 'firstName', label: 'First Name' },
    { name: 'lastName', label: 'Last Name' },
  ];
  
  function ChildComponentOfDndProvider() {
    const [query, setQuery] = useState<RuleGroupType>({ combinator: 'and', rules: [] });
  
    return (
      <QueryBuilderDndWithoutProvider dnd={{ ...ReactDnD, ...ReactDndBackend }}>
        <QueryBuilder fields={fields} defaultQuery={query} onQueryChange={setQuery} />
      </QueryBuilderDndWithoutProvider>
    );
  }
  
  export function App() {
    return (
      <ReactDnD.DndProvider backend={ReactDndBackend.HTML5Backend}>
        <SomeOtherDndContextConsumer />
        <ChildComponentOfDndProvider />
      </ReactDnD.DndProvider>
    );
  }
