JavaScript/jQuery List Options

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.

Type:

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.

Type:

Default Value: false

bounceEnabled

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

Type:

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.

Type:

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.

Type:

|

Array<String | dxListItem | any>

|

Store

|

DataSource

|

DataSource Configuration

| null

Default Value: null

The List works with collections of string values or objects.

Depending on your data source, bind 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.

jQuery

JavaScript

$(function() {
    let serviceUrl = "https://url/to/my/service";

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.

When this property is true, make sure that all data source objects have the following structure:

JavaScript

const dataSource = [{
    key: "Group 1", // Group caption 
    items: [ // Items in the group
        { ... },
        { ... }
    ]
}, {
    // ...
}];

You can supply data to this structure using the DataSource object's group property.

NOTE

Only one-level grouping is supported.

groupTemplate

Specifies a custom template for group captions.

Type:

template

Template Data:

The current group's data.

Default Name: 'group'

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.

Type:

Default Value: undefined

hoverStateEnabled

Specifies whether the UI component changes its state when a user pauses on it.

Type:

Default Value: true

indicateLoading

Specifies whether or not to show the loading panel when the DataSource bound to the UI component is loading data.

Type:

Default Value: true

NOTE

This property affects only the load panel displayed when the bound DataSource is loading data after the load() method is called. The load indicator displayed when the list is being updated is always enabled regardless of the property value.

itemDeleteMode

Specifies the way a user can delete items from the list.

Type:

ItemDeleteMode

Default Value: 'static', 'slideItem' (iOS), 'swipe' (Android)

NOTE

If List items are supplied with the context menu, this property is ignored in favor of the menuMode property.

itemDragging

Configures item reordering using drag and drop gestures.

Type:

Sortable configuration

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

itemHoldTimeout

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

Type:

Number

Default Value: 750

items[]

An array of items displayed by the UI component.

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.

itemTemplate

Specifies a custom template for items.

Type:

template

Template Data:

The item object to be rendered.

Default Name: 'item'

Type:

ListMenuMode

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

nextButtonText

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

Type:

Default Value: 'More'

noDataText

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

Type:

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.
