Layout Component
The Layout component is currently being beta-tested.
Thunkable’s Layout component allows for more precise positioning of UI components on an app screen, by allowing you to position UI components dependent on other UI components on the screen. For example, in a typical sign-in screen, if a user inputs an incorrect email address or password, a screen built with a Layout component allows you to shift the UI components on the screen to display the error messaging to the user.
To add a Layout to a screen:
- 1.Drag and drop the Layout UI component onto a screen. You’ll notice it is composed of two Containers, one on top of the other.
- 2.Click and drag the sizing handles in the corners to resize the Layout UI component.
- 3.Click and drag to reposition it.
By default, a newly added Layout has two horizontal Containers arranged vertically, one on top of the other. To insert additional Containers to a Layout:
- 1.Click to select the Layout UI component in the component tree or within the screen.
- 2.At the top of the Layout’s properties panel, select whether you want to insert a Horizontal or Vertical Container. ∙ Horizontal Container - UI components within the Container are aligned horizontally, side by side ∙ Vertical Container - UI components within the Container are aligned vertically, on top of each other
- 3.Identify into which Layout or Container you want to insert the new Container.
- 4.Click Add.
To add UI components to a Layout:
- 1.Drag and drop UI components into a Container on a screen.
- 2.Once UI components are in a Container, rearrange their order by dragging and dropping their component names in the component tree.
The following properties are configured on the right in the Layout's properties panel.

To access the blocks specific to the Container component:
- 1.Navigate to the Blocks tab.
- 2.In the component tree on the left, click the Container component that is nested under the Layout component.
- 3.A drawer of Container-specific blocks opens.
- 4.The blocks are the same as the ones above in the Layout Blocks section, but specific to the Container instead of the Layout.
The layout component is the foundation of custom data viewers, which allow for more precise positioning of UI components on an app screen.
