Angular Sortable Properties

This section describes properties that configure Sortable UI component content, behavior, and appearance.

Angular
Vue
React

allowDropInsideItem

Allows a user to drop an item inside another item.

Type:

Boolean

Default Value: false

This property also requires that you handle the change of hierarchy in code. If an item is dragged within a single component, use the onReorder handler. If the item is dragged from one component to another, use the onAdd and onRemove handlers.

See Also

allowReordering

Allows a user to reorder sortable items.

Type:

Boolean

Default Value: true

This property limits row reordering to the UI and does not affect the data source. You should also handle the effects of the drag and drop to the data source in code. If users reorder items inside a single component, implement the onReorder handler.

To configure drag and drop between components, follow the instructions from the group topic.

dropFeedbackMode

Specifies how to highlight the item's drop position.

Type:

String

Default Value: 'push'
Accepted Values: 'push' | 'indicate'

This property accepts the following values:

    Items move apart with animation, allowing room for the dragged item to be placed. To use this mode, ensure that the allowDropInsideItem is disabled.

  • "indicate"
    Items do not animate, a blue square appears at the place where the dragged item is going to be placed.

        );

export default App;

filter

Specifies a CSS selector for the items that can be dragged.

Type:

String

Default Value: '> *'

group

Allows you to group several UI components, so that users can drag and drop items between them.

Type:

String

Default Value: undefined

Set this property to identical values for the UI components you want to collect into a single group. This allows users to drag and drop items between components, but only in the UI. To handle drag and drop in code, implement the onAdd and onRemove handlers. Both these handlers are executed simultaneously when an item is dropped to the target component, but onAdd is executed in the target component, while onRemove is executed in the source component.

handle

Specifies a CSS selector (ID or class) that should act as the drag handle(s) for the item(s).

Type:

String

Default Value: ''

height

Specifies the UI component's height.

Type:

Number

|

String

|

Function

Return Value:

Number

|

String

The UI component's height.

Default Value: undefined

This property accepts a value of one of the following types:

  • Number
    The height in pixels.

  • String
    A CSS-accepted measurement of height. For example, "55px", "20vh", "80%", "inherit".

  • Function (deprecated since v21.2)
    Refer to the W0017 warning description for information on how you can migrate to viewport units.

itemOrientation

Notifies the UI component of the items' orientation.

Type:

String

Default Value: 'vertical'
Accepted Values: 'horizontal' | 'vertical'

moveItemOnDrop

Moves an element in the HTML markup when it is dropped.

Type:

Boolean

Default Value: false

jQuery

We recommend that you set moveItemsOnDrop to true because changes to the data model do not automatically update the HTML markup. If you set this property to false, you should move DOM nodes in the onReorder function.

Angular

We recommend that you set this property to false. In Angular, the HTML markup depends on the data model and is updated automatically when you make changes.

Vue

We recommend that you set this property to false. In Vue, the HTML markup depends on the data model and is updated automatically when you make changes.

React

We recommend that you set this property to false. In React, the HTML markup depends on the data model and is updated automatically when you make changes.
