Templates in React Dialog component

28 Jul 2021 / 3 minutes to read

In Dialog the template support is provided to header, content and footer sections. So any text or HTML content can be appending in these sections.

The Dialog header content can be provided through the header property, and it will allow both text and any HTML content as a string. Also in header, close button is provided as built-in support, and this 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 can be provided through the content property, and it accepts both text and HTML string as content.

The below example demonstrates the usage of header, footer and content template in the Dialog.
