JavaScript/jQuery ContextMenu Options

An object defining configuration properties for the ContextMenu UI component.

accessKey

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

Type:

String

| undefined
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:

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.

animation

Configures UI component visibility animations. This object contains two fields: show and hide.

Type:

Object

Default Value: { show: { type: 'fade', from: 0, to: 1, duration: 100 }, hide: { type: 'fade', from: 1, to: 0, duration: 100 } }

Set this object to null or undefined to disable animation.

closeOnOutsideClick Deprecated

Use the hideOnOutsideClick property instead.

Specifies whether to close the UI component if a user clicks outside it.

Type:

Boolean

|

Function

Function parameters:
event:

Event (jQuery or EventObject)

The event that caused UI component closing. It is a EventObject or a jQuery.Event when you use jQuery.

Return Value:

Boolean

true if the UI component should be closed; otherwise false.

Default Value: true

cssClass

Specifies the name of the CSS class to be applied to the root menu level and all submenus.

Type:

String

Default Value: ''

Use this property to customize the current menu in isolation from other menus created on the same page.

dataSource

Binds the UI component to data.

Default Value: null

The ContextMenu works with collections of string values or objects.

Depending on your data source, bind ContextMenu 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.

  • 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.

    JavaScript
    • $(function() {
    • let serviceUrl = "https://url/to/my/service";
    • $("#contextMenuContainer").dxContextMenu({
    • // ...
    • dataSource: DevExpress.data.AspNet.createStore({
    • key: "ID",
    • loadUrl: serviceUrl + "/GetAction",
    • insertUrl: serviceUrl + "/InsertAction",
    • updateUrl: serviceUrl + "/UpdateAction",
    • deleteUrl: serviceUrl + "/DeleteAction"
    • })
    • })
    • });
  • Any other data source
    Implement a CustomStore.

Regardless of the data source on the input, the ContextMenu 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 ].

  • 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.

disabled

Default Value: false

disabledExpr

|

Function

Function parameters:

Set this property to the name of a data field that provides displayed values...

  • // "item" can be null
  • return item && 'ID: ' + item.id + ', Name: ' + item.name;
  • }

elementAttr

Specifies the global attributes to be attached to the UI component's container element.

Type:

  • $(function(){

|

Function

Function parameters:

Event (jQuery or EventObject)

The event that caused UI component hiding. It is a EventObject or a jQuery.Event when you use jQuery.

Return Value:

Boolean

true if the UI component should be hidden; otherwise false.

Default Value: true

The function passed to this property enables you to specify a custom condition for UI component hiding. For instance, you can prevent hiding until a user clicks a certain element.

JavaScript
  • $(function () {
  • $("#contextMenuContainer").dxContextMenu({
  • // ...
  • hideOnOutsideClick: function(e) {
  • return e.target === $("#someElement").get()[0];

| undefined
Default Value: undefined

hoverStateEnabled

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

Type:

Boolean

Default Value: true

items[]

Holds an array of menu items.

Raised Events: onOptionChanged

The items array can contain:

  • 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
  • contextMenuInstance.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.

itemsExpr

Specifies which data field contains nested items.
