Paths after Voiceglow multiselect button

There are buttons that users can click but there is the multiselect button. If he clicks 1 button it will show a corresponding card with the product he chose. I want to make it so if a user selects 2 or more buttons (chair types in this case) it will show him either a carousel of cards or just separate cards of products he chose. So for example if he chooses the office chair and the outdoor chair, it will then show the user cards for both of these products. I tried something with if conditions, but even If I select 2 or more buttons it will only take me to one of them. Can someone help me with that?
