Markup Components

This section describes components that can be used when defining a UI component markup.

dxItem

Specifies markup for a UI component item.

import { dxItem } from "devextreme/ui/widget/ui.widget"
Type: any

The dxItem component defines custom markup for items in layout and collection UI components. dxItem has different properties depending on the UI component where it is used. For a full list of them, see the items property description in a specific UI component's API Reference.

NOTE
dxItem elements are ignored when the dataSource property is defined.

dxTemplate

A custom template's markup.

Included in: dx.web.js, dx.all.js
import { dxTemplate } from "devextreme/core/templates/template"
Type:

Object

The dxTemplate markup component specifies a custom template for a container UI component or a collection UI component's items in Angular, AngularJS and Knockout apps. Place this template within the UI component's element, specify the template name and assign it to the corresponding xxxTemplate property (for example, itemTemplate, containerTemplate). You can omit specifying the xxxTemplate property if you use the default template name, for instance, item for the itemTemplate, content for the contentTemplate.

Commonly, the dxTemplate is in the component's (Angular), scope's (AngularJS) or view model's (Knockout) binding context, but it can differ depending on the UI component element you specify the template for. See the corresponding xxxTemplate property description for more information on a specific template's binding context. Use Knockout or AngularJS binding variables if you need to access another binding context from the template.

When you specify an item template in Knockout apps, you can bind this template's elements directly to an item object's fields. In Angular and AngularJS apps, an item object extends the standard binding context. In AngularJS apps, you can access it only using an alias that you specify in the dx-item-alias directive. In Angular apps, use the input variable that is declared via the let keyword. In all Angular, AngularJs and Knockout apps, you can also bind a template element to the rendered item's index using the index keyword.

In AngularJs and Knockout apps, you can define different templates intended for different devices. Specify the device object's fields as the dxTemplate's markup properties to set a target device for a template.

JavaScript
<div data-options="dxTemplate: { name: 'item', platform: 'ios', phone: true }">
    This is a template for an iPhone.
</div>
<div data-options="dxTemplate: { name: 'item', tablet: true }">
    This is a template for any tablet.
</div>
