Introduction
FormKit’s Drag and Drop is a small library for adding drag and drop functionality to your app. It’s simple, flexible, framework agnostic, and clocks in at only ~5kb gzipped. Drag and Drop works with React, Solid, Vue, Svelte, or any JavaScript framework. This library differs from others in the way the drag and drop operations are performed. Rather than moving elements around the DOM manually, Drag and Drop updates the reactive data model used by the provided render function.
Getting Started
Install
Drag and Drop is published as @formkit/drag-and-drop on npm. Click to copy the install command for your package manager of choice:
- npm install @formkit/drag-and-drop
- pnpm add @formkit/drag-and-drop
- yarn add @formkit/drag-and-drop
- bun install @formkit/drag-and-drop
Usage
Drag and drop ships two main functions: dragAndDrop and useDragAndDrop. These can be imported for your framework of choice by using the subpath import @formkit/drag-and-drop/{react/vue/solid}. A native JavaScript version of the dragAndDrop function is also available at @formkit/drag-and-drop.
Whichever method you choose, the core concept remains the same: FormKit's Drag and Drop accepts two main arguments — the parent element containing the draggable items and the data that those items represent.
useDragAndDrop
The useDragAndDrop hook is the most convenient way to add Drag and Drop to your app and is available for React, Vue, and Solid. Call this function with an initial array of values and the configuration options. It returns an array of values containing a a template ref, a reactive set of values (and a setter in the case of React), as well as a function to update the parent's config. The template ref should be assigned to the parent DOM element of the items you wish to make draggable. The reactive array of values should be used in your template to render the draggable elements.
// Example parent configuration object:const config = { sortable: false }
// React:const [parentRef, values, setValues, updateConfig] = useDragAndDrop(
['Item 1', 'Item2', 'Item3'],
config
)
// Vue:const [parentRef, values, updateConfig] = useDragAndDrop(
['Item 1', 'Item2', 'Item3'],
config
) dragAndDrop
The dragAndDrop hook allows you to define your own ref and list state. This is useful if you need to integrate with a pre-existing app without changing your component structure.
// Example parent configuration object:const config = { sortable: false }
// React:dragAndDrop({
parent: parentRef,
state: [values, setValues],
config
})
// Vue:dragAndDrop({
parent: parentRef,
values: valueRef,
config
})
// Vanilla JS: (import from core, not subpath)
dragAndDrop({
parent: HTMLElement,
getValues: () => {
// Return array of values
},
setValues: (newValues) =>
// Do something with updated values
},
config
}) Core Features
Sortability
Using useDragAndDrop or dragAndDrop automatically makes a lists sortable. Dragging items within your list will automatically change your list’s state to reflect the new order (which in turn allows the framework to re-render to the correct order):

- Vue
- Solid

Draggable
For drag-and-drop to function correctly, the length of array of values provided must be equivalent to the number of immediate children to the parent element. If they are not, a console warning will appear: The number of draggable items in the parent does not match the number of values, which may lead to unexpected behavior." The most common cause of this is when the parent element has an immediate child that is not meant to be draggable. In this case, the configuration property draggable can be set to a callback function that lets you determine whether or not a given element should be draggable:

Transferability
In addition to sorting, drag-and-drop allows transferring values between parents (lists). To enable this, set the configuration property group to the same value for each list that should allow value transfers. Notice in the example below that items can be appended to the end of the list by hovering over the list itself, or inserted into the list by hovering over the target parent's draggable items.

Plugins
Plugins are a powerful way to extend the functionality of the library. They can be used to add new features, modify existing ones, or even create entirely new experiences.
Drop or Swap
The examples seen so far have shown the values of a given list being updated as the end-user drags over the list and its children. To enable behavior where the values of the list are only updated when the user drops the item, use the dropOrSwap plugin.

Events
When using a drag and drop library, often it is useful to be able to listen to particular events, such as when a drag starts or ends. Event listeners can be set at either a global level or at the parent level.
Global
Two global events are available, `dragStarted` and `dragEnded`. In order to listen to global events, import the state object from @formkit/drag-and-drop and register your event listener using the on method.

Parent
Parents themselves have their own set of events that can be listened to. These events include: `onDragstart`, `onDragend`, `onSort`, `onTransfer`. To listen to parent events, assign a callback function to the event in the parent's configuration object.

Configuration
Each parent can be passed a configuration object. This object can be used to set options like group, drag handles, and or more dynamic options such as determining which direct descendants of a list are draggable. Invocation of useDragAndDrop or dragAndDrop can be used idempotently to update the configuration for a given list.
