Angular TabPanel - items

An array of items displayed by the UI component.

Selector: dxi-item
Type:

Array<String | dxTabPanelItem | 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
tabPanelInstance.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.

badge

Specifies a badge text for the tab.

Type:

String

disabled

Specifies whether the UI component item responds to user interaction.

Type:

Boolean

Default Value: false

html

Specifies the HTML markup to be inserted into the item element.

Type:

String

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

You can use the text property as a safe alternative.

icon

Specifies the icon to be displayed in the tab's title.

Type:

String

This property accepts one of the following:

tabTemplate

Specifies a template that should be used to render the tab for this item only.

Type:

template

Template Data: undefined

The following types of the specified value are available.

  • Assign a string containing the name of the required template.
  • Assign a jQuery object of the template's container.
  • Assign a DOM Node of the template's container.
  • Assign a function that returns the jQuery object or a DOM Node of the template's container.

template

Specifies a template that should be used to render this item only.

Type:

template

Template Data:

CollectionWidgetItem

The item object to be rendered.

The following types of the specified value are available.

  • Assign a string containing the name of the required template.
  • Assign a jQuery object of the template's container.
  • Assign a DOM Node of the template's container.
  • Assign a function that returns the jQuery object or a DOM Node of the template's container.

The following example adds a custom item to the component. Note that Angular and Vue use custom templates instead of the template property. In React, specify the render or component properties.

jQuery
index.js
$(function() {
    $("#tabPanelContainer").dxTabPanel({
        // ...
        items: [
            {
                // ...
                template: '<div>Custom Item</div>'

text

Specifies text displayed for the UI component item.

Type:

String

title

Specifies the item title text displayed on a corresponding tab.

Type:

String

NOTE

In Angular, the title's value can also be passed to browser tooltip. This happens because this property has the same name as the HTML attribute that specifies the tooltip's text.
To avoid this behavior, wrap the property in square brackets and wrap the property value in single quotes:

HTML
<dxi-item [title]="'Customers'">
