Preview a layout

Preview mode

Preview mode in Rails Builder enables you to visualize how a layout will look in the TV app. This is particularly useful when you’ve created a new layout or made changes to an existing one.

To preview a layout:

  1. Click the Preview button at the top right of the layout screen.

  2. Select a device format using the tabs at the top of the screen:

    • Monitor

    • Tablet

    • Phone Landscape

    • Phone Portrait

  3. To close the preview and return to the Rails Builder layout screen, click the blue Layout button at the top right of the screen.
