Use the **Applies to** section to choose where a size chart appears on your storefront.

## Selecting products and collections

Click **Select products**, **Select collections**, or both. Each selection appears as a removable chip, so you can update the assignment without starting over.

When you have not made a selection, the section shows “No products or collections are selected”.

## At least one is required

You must select at least one product or collection before you can publish a chart. If you try to save without a selection, Icona shows “Select at least one product or collection”.

## When a product matches more than one chart

If more than one published chart covers the same product, Icona shows the chart that was published most recently.
