Vue List Props

An object defining configuration properties for the List UI component.

accessKey

Specifies the shortcut key that sets focus on the UI component.

Selector: access-key
Type:

String

Default Value: undefined

The value of this property will be passed to the accesskey attribute of the HTML element that underlies the UI component.

activeStateEnabled

Specifies whether the UI component changes its visual state as a result of user interaction.

Selector: active-state-enabled
Type:

Boolean

Default Value: true

The UI component switches to the active state when users press down the primary mouse button. When this property is set to true, the CSS rules for the active state apply. You can change these rules to customize the component.

Use this property when you display the component on a platform whose guidelines include the active state change for UI components.

allowItemDeleting

Specifies whether or not an end user can delete list items.

Selector: allow-item-deleting
Type:

Boolean

Default Value: false

bounceEnabled

A Boolean value specifying whether to enable or disable the bounce-back effect.

Selector: bounce-enabled
Type:

Boolean

Default Value: true, false (desktop)

If the property is set to true, you can scroll the list content up (down) even if you have reached the bottom (top) boundary. But when you release the content, it returns to the bound position. If the property value is false, you can scroll the list content until you reach the boundary.

collapsibleGroups

Specifies whether or not an end user can collapse groups.

Selector: collapsible-groups
Type:

Boolean

Default Value: false

This property makes sense if the grouped property is set to true.

If the collapsibleGroups property is set to true, the down arrow is displayed to the right of a group header. An end user can collapse or expand a group simply clicking the group header.

dataSource

Binds the UI component to data.

Selector: data-source
Default Value: null

The List works with collections of string values or objects.

Depending on your data source, bind the List to data as follows. If the data source provides objects, also specify the itemTemplate. You can skip this part if the objects contain fields described in the items section.

  • Data Array
    Assign the array to the dataSource option. View Demo

  • Read-Only Data in JSON Format
    Set the dataSource property to the URL of a JSON file or service that returns JSON data.

  • OData
    Implement an ODataStore.

  • Web API, PHP, MongoDB
    Use one of the following extensions to enable the server to process data according to the protocol DevExtreme UI components use:

    Then, use the createStore method to configure access to the server on the client as shown below. This method is part of DevExtreme.AspNet.Data.

  • Any other data source
    Implement a CustomStore.

Regardless of the data source on the input, the List always wraps it in the DataSource object. This object allows you to sort, filter, group, and perform other data shaping operations. To get its instance, call the getDataSource() method.

NOTE

Review the following notes about data binding:

  • Do not specify the items property if you specified the dataSource, and vice versa.

  • Data field names cannot be equal to this and should not contain the following characters: ., :, [, and ].

jQuery
  • The stores are immutable. You cannot change their configurations at runtime. Instead, create a new store or DataSource and assign it to the dataSource property as shown in the following help topic: Get and Set Properties.
Angular
  • The stores are immutable. You cannot change their configurations at runtime. Instead, create a new store or DataSource and assign it to the dataSource property as shown in the following help topic: Two-Way Property Binding.
Vue
  • The stores are immutable. You cannot change their configurations at runtime. Instead, create a new store or DataSource and assign it to the dataSource property as shown in the following help topic: Two-Way Property Binding.
React
  • The stores are immutable. You cannot change their configurations at runtime. Instead, create a new store or DataSource and assign it to the dataSource property as shown in the following help topic: Controlled Mode.

itemDragging

Configures item reordering using drag and drop gestures.

Selector: DxItemDragging

See the Sortable configuration for properties that you can specify in this object.

View Demo

itemHoldTimeout

The time period in milliseconds before the onItemHold event is raised.

Selector: item-hold-timeout
Type:

Number

Default Value: 750

items[]

An array of items displayed by the UI component.

Selector: DxItem
Type:

Array<String | dxListItem | any>

Raised Events: onOptionChanged

The items array can contain:

  • Strings
  • Objects with fields described in this section
  • Objects with any other fields. In this case, specify the itemTemplate.

If you need to update the UI component items, reassign the entire items array as shown in the following example:

JavaScript
listInstance.option('items', newItems);

As an alternative to items, you can use the dataSource property. It accepts the DataSource object, whose underlying stores provide an API that allows you to update individual items without reassigning the entire item collection.

NOTE
Do not use the items property if you use dataSource, and vice versa.

View Demo

itemTemplate

Specifies a custom template for items.

Selector: item-template
Type:

template

Template Data:

Object

The item object to be rendered.

Default Name: 'item'

|

Function

Default Value: null

Specifies the array of items for a context menu called for a list item.

Selector: DxMenuItem

Default Value: 'context', 'slide' (iOS)

nextButtonText

The text displayed on the button used to load the next page from the data source.

Selector: next-button-text
Type:

String

Default Value: 'More'

noDataText

Specifies the text or HTML markup displayed by the UI component if the item collection is empty.

Selector: no-data-text
Type:

String

Default Value: 'No data to display'

The List component evaluates the noDataText property's value. This evaluation, however, makes the List potentially vulnerable to XSS attacks. To guard against these attacks, encode the HTML markup before you assign it to the noDataText property. Refer to the following help topic for more information: Potentially Vulnerable API - noDataText.
