Template in React Dialog component

20 Feb 202623 minutes to read

The Dialog supports templating for the header, content, and footer sections. Text and HTML content can be appended to these sections through template properties.

The Dialog header content is provided through the header property, which accepts both text and HTML content as a string. A close button is also provided as built-in support and can be enabled through the showCloseIcon property.

The Dialog footer can be enabled by adding built-in buttons or providing any HTML string through the footerTemplate.

The buttons and footerTemplate properties can’t be used at the same time.

Content

The Dialog content is provided through the content property, which accepts both text and HTML strings.

The following example demonstrates the usage of header, footer, and content templates in the Dialog.
