Layout Component

The Layout component is currently being beta-tested.

Overview

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.

Add a Layout to a Screen

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.

Insert Additional Containers

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.

Add UI Components

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.

Container Blocks

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.

Create a Custom Data Viewer

Thunkable provides a variety of default Data Viewer List and Data Viewer Grid templates, but saving a customized Layout component as a Data Viewer allows you to display your data in a way that reflects your brand design and preferences.

To save a Layout as a Data Viewer:

1. When you're happy with the Layout you have customized, ensure it is selected in the component tree.

2. Click the vertical ellipsis next to the Layout's name in the properties panel.

3. Select Save as Data Viewer Layout.

   
4. Give your Data Viewer Layout a detailed name.

5. Select the Layout Type you want to create. - List for a Data Viewer List - Grid for a Data Viewer List.

6. Click OK.

To use a saved Layout as a Data Viewer:

1. Click the Create New Screen icon at the top of the component tree in the Designer.

2. Drag a Data Viewer List or Data Viewer Grid onto your screen.

3. Reposition and resize as necessary.

4. Connect you project to a data source. See here for instructions on connecting a data source: Data Sources.

5. Click the sample template to access the Data Viewer templates available to you.

   
6. Click to select the Layout you saved as a Data Viewer from the bottom of the template library.

7. Map your data source columns to components within your custom Data Viewer Layout.
