Retool now supports 15 preset chart components, eliminating the need to manually write Plotly JSON for basic chart types. This change enables users to more easily create and customize chart and graphs in their apps.

Features of the new chart components include:

• Support for multiple data sources in series-based charts.
• Data grouping and aggregation.
• Customizeable titles, legends, labels, and toolbars.
• Configurable user interactivity.
• Advanced use cases using the Plotly JSON Chart.

An updated Theming experience is now available. Users on the Business and Enterprise plans can now see a revamped organization-level theme editing experience with expanded functionality, including:

• The ability to create custom color, typography, and metric tokens for use in the theme editor and app component styles.
• The ability to create multiple modes within a theme and switch between modes in an app using theme.setMode().
• The ability to configure default styles for individual components, as well as bulk edit shared styles for multiple components at once.
• Expanded typography controls—including the ability to configure multiple fonts in a theme using a CSS import or Google Fonts, set a default font family, and control font family and font weight for headings.

For users on all plans:

• Component-level font weight and font family style controls.
• A refreshed app-level theme experience with expanded typography controls.
• An updated component style editing experience.

Retool will deprecate the use of YAML for protected apps, queries, and resources in Source Control. Support will be removed in the Q2 2025 stable release of Self-hosted Retool.

Self-hosted organizations still using YAML serialization of these elements in Source Control must migrate to Toolscript prior to upgrading.

A new version of the Alert component is now available. It is a significant upgrade over the previous version, with new options to customize alert messaging.

You can create custom alert states that represent different alert types or severity, and configure them with the following options:

• Title and description.
• Icon, icon position, and tooltip.
• Action text to trigger event handlers on click.

Existing apps can continue to use the previous version, which is now deprecated.

A new version of the Scanner component is now available. It is a significant upgrade over the previous version, with new functionality for you to customize the scanning experience. Features include:

• Use scan events to reference scanned items and the time between scans.
• Detect duplicate scans.
• Programmatically pause after each scan or set the time between scans.

The Comment Thread component enables users to post comments and start discussions directly within your apps. All users who have access to an app that contains Comment Thread can use the component. Each user's comment appears with their name and avatar image.

When using Comment Thread, you specify a unique thread ID with which to associate comments. This can be a dynamic value so that comment threads dynamically change based on user interactions. For example, setting the thread ID to {{ table1.selectedRow.id }} would associate comments to whichever row is currently selected.

Comment Thread includes event handler support, action buttons, and granular control over the refresh period. Retool automatically handles comment storage and retrieval so no data source is needed.

If you're currently using the Comment component, you can switch to using Comment Thread without losing previous conversations by using the current Evaluated key value as the thread ID.

Retool released a new version of the List View component in December 2023. The previous version has continued to be available as the Legacy List View component. You can continue to use the Legacy List View component in existing apps but we recommend you switch to using the newer List View component. The newer version of List View is much more performant, has more features, and will receive updates.

Feature comparison​

Learn more about the differences between Legacy List View and List View.

Feature	Legacy List View	List View
Number of instances	Set the instances property value.	Automatically generated for each array item in data.
Instance values	Reference nested values using the item index (e.g., textInput1[3].value).	Nested components cannot be referenced outside of List View. For form inputs, use instanceValues instead.
Instance keys	Item keys.	Primary keys.
Auto-height	Automatically grows with content.	Requires a suitable maxHeight value.
Show border	Yes	Nest the List View component within a container and use it to set the border.
Show drop shadow	Yes	Nest the List View component within a container and use it to set the drop shadow.
Styles and nested styles	Yes	Nest a container within List View to apply styles and nested styles.

Instance keys and values​

Retool recommends using primary keys, a unique identifier, to track and restore instances within the List View.

List View is virtualized and only evaluates and renders items currently visible. This significantly improves performance. However, this also means that you can no longer directly reference nested items as they may not have been evaluated yet. Instead, you can reference instance values for forms and input components.

Appearance settings​

List View supports all of the same appearance settings as Legacy List View, with the following exceptions:

• List View does not support border or drop shadow styles. Instead, nest a container within List View and configure it with a border and drop shadow.
• A List View with a heightType of auto requires a suitable maxHeight value to maintain performance. The default is 100vh and you can specify a different value to use. You should consider using the container in which List View is nested to avoid unexpected scrollbars.

The Stack component is a container with Flexbox-like layout controls. Instead of following the standard 12-column grid layout, Stack automatically arranges nested components horizontally or vertically. You can then control the alignment and distribution of nested components and precisely adjust component size.

Multipage apps contain pages to combine functionality and use cases. Standard Retool apps operate as single-page applications where all code and components is continually evaluated. Multipage apps are also supported by Retool Mobile where each screen functions as a separate page.

With multipage apps, Retool only evaluates the code and components of the page currently in view. The benefits of multipage apps include:

• Greater performance of large and complex apps. Since Retool only evaluates code and components for the current page, multipage apps are 30-40% faster than a single-page app.
• Seamless navigation between pages. Retool loads the complete app state whenever a user navigates to a single-page app. With multipage apps, navigation between pages is seamless and more responsive.
• Improved app management. Multipage apps can replace multiple apps in your organization, such as a team's frequently used apps. This reduces the number of apps to maintain and allows for easier permission management.
• Reduced module dependency. Modules are commonly used to create shared navigation menus across multiple single-page apps. With multipage apps, you can eliminate the need for additional modules and the complexities with maintaining them.

Each multipage app uses global and page scopes to separate pages. Globally scoped code, and Header and Sidebar frames, are available for use across every page, while each page has its own page-scoped code and components.

You can request access to the multipage app beta and explore the docs to learn more.

Retool is currently working on a new layout architecture, WidgetGrid, that significantly improves the performance of the canvas. Placement and arrangement of components, such as dragging to reposition, is up to 50% more responsive.

WidgetGrid is currently rolling out to cloud-hosted organizations as an opt-in beta and will be available in the next Edge release of self-hosted Retool. You can enable WidgetGrid from the status bar when viewing or editing an app. You can disable WidgetGrid at any time and provide feedback about any issues you experienced.
