In the Variation Monster plugin, the “Selected Icon Template” setting allows you to choose how the checkmark icon appears when a variation swatch is selected. There are two template styles available:

1. Center Checkmark – Displays the checkmark in the middle of the swatch button.
2. Top-Right Circle Checkmark – Displays the checkmark inside a small circle positioned at the top-right corner of the swatch.

This configuration helps enhance the visual clarity of selected variations, allowing you to match the style that best fits your product design and user experience.
