The React Dialog is a useful user interface (UI) component for informing users about critical information, errors, warnings, and questions, as well as confirming decisions and collecting input from users. The component has a rich set of built-in features such as action buttons, positioning, animations, dragging, resizing, templating, and more with mobile dialog support. The Dialog includes modal dialogs and non-modal dialogs (modeless) based on interactions.

The React Dialog component comes with two different types of dialogs, modal and non-modal (modeless):

  • Modal dialogs force users to interact with them before continuing. They are used to show important interaction information and non-continuous process information (for example, a sign-up or login form).
  • Non-modal dialogs allow users to interact outside the dialog box even if it is in an active state, which is suitable for frequent and nonblocking dialogs (for example, find and replace dialogs).

Dialog UI elements

The React Dialog component provides headers (titles), body (content), and action area/footer for better customization.

Action buttons

The React Dialog component provides built-in support to perform actions through buttons, which define necessary callback functions to handle user input.


Users can position a dialog wherever they want in a page. It is easy to configure this through built-in positions or any custom axis value (for example: top left, bottom right, top right, bottom left, 100 75).


A modal Dialog box in React can be moved anywhere in a page by dragging its header, which performs using the Draggable library.


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

Localization in React Modal Dialog


Localization library allows to localize the default text content of Dialog. In Dialog, the close button’s tooltip text alone will be localize based on culture.


The following content provides the exact CSS structure that can be used to modify the control’s appearance based on the user preference.

Appearance in React Modal Dialog


Modal dialogs create overlays on open modal windows that provide options for a user to control the closing behavior of a dialog while interacting with it.

Additional dialogs

Users can launch multiple dialogs simultaneously or one above the other based on their z-index (z-depth) to make additional dialogs (nested modal dialogs).


A variety of smooth, built-in animations are available to configure for the opening and closing of modal dialogs. They perform based on CSS3 animation from the Animation library.


The modal dialog can resize from any of the edges or borders of the dialog within the target container by using its handle (grip) or hovering on it.

Close options

A modal dialog can be closed by clicking on a close icon, with an overlay click, or by pressing the ESC key. Users can restrict the closing behavior of a dialog based on its callback function parameters, also.

Remote content via AJAX

Users can directly load content from a remote source (like an external webpage) into a dialog using the AJAX library.

Alert and confirmation dialogs

Create React alerts and confirmation dialogs using built-in functions.

Right-to-left (RTL)

The React Dialog component supports right-to-left (RTL) rendering. Users can change the text direction and layout of the Dialog component to RTL. This improves the user experience and accessibility for those who use RTL languages.

React Dialog covers web accessibility


  • Fully supports WAI-ARIA accessibility, which helps dialogs be accessed by on-screen readers and assistive devices.

  • Follows WAI-ARIA Best Practices for implementing keyboard interaction.

  • Follows the WCAG 2.0 standard in the design of UI element visuals such as foreground color, background color, line spacing, text, and images.

React Dialog works well in touch devices


The React Dialog component is highly configurable to give mobile dialogs better user experiences across phone, tablet, and desktop form factors.


The React Dialog component has several built-in themes such as Material, Bootstrap, Fabric (Office 365), Tailwind CSS, and High Contrast. Users can customize any one of these built-in themes or create new themes to achieve their own desired look and feel either by simply overriding SASS variables or using our Theme Studio application.

Developer-friendly APIs

Developers can control the appearance and behaviors of a dialog, including its positioning, content, and animation, using a rich set of APIs.

Other supported frameworks

The Modal Dialog component is also available in Blazor, Vue, Angular, and JavaScript frameworks. Check out the Dialog in different platforms from the following links:
