The Go to Tab action allows you to move the user to a specific tab in your app.
This is different from the Show New Screen action which allows you to link to a sheet and customize that screen however you like. With Go to Tab, you have to already have created a Tab so the action can move the user there.
Click on the plus (+) sign in the Components panel and select the Component you want to trigger the action.
In the General tab on the right side of the Layout Editor, navigate to the Actions section and select Go to Tab.
Select the icon and descriptive text to use in your app, and then choose the Tab you the user to go to.
You can optionally add Conditions for certain criteria to be met before a user can trigger this action.
Select the + New Action button. If you have existing actions, click on the plus (+) sign in the left panel.
Select the data source for your action.
Configure your first action by clicking the first action in the sequence. You can also add Conditions to your actions, if needed.
To add new actions to the flow, hover just underneath an action and click the plus button. In this way you can add the Go to Tab action as just one step in a larger workflow.
Check the Introduction to Actions page for a full list of components that can be used to trigger actions.
