Add a number input to the screen. Rename it “Order # Input” and set the default value to 0. Hide the input under a rectangle or make it transparent by deselecting background, border, and set the text and placeholder text color transparency to 0.
Add your list of orders on the left below the input.
Set an action to update the input to the current order #.
Add another list on the right side of the screen to display more information. You can add a list within the list of order items.
So here I have a list of orders where order # is equal to order # input with a visibility setting where order # input is not equal to 0. Set the maximum to 1.
Last, I added this “Select an order to continue” to display if the order # input is equal to 0.
