Insert the component which you need to repeat (e.g., a Text Input) into a parent component which can repeat its children (e.g., a Layout Stacked).

Repeat the child component using the parent component's Subcomponents tab.

Optionally, rename the Item Name to a more descriptive value.

Map the child's variables via the child's mapping dialog using the Item Name value.

Select the component or any of its parent components and map its array to another array.

After mapping the arrays, map their variables.
