Hi all,
I'm currently building an mobile app for mobile phones and tablets where you can choose multiple sorts of wine from a gallery.
I want to collect the selected item to a collection and adjust the background and border color as soon as I select the items.
I thought I could do this with an overlay button in the containter, but I'm using a vertical container for responsive design support and the button is always at the bottom of the container.

Is there a way to add an button above all items in an vertical container? Or do you have another idea to accomplishe this?
When I'm inserting the labels directly to the gallery template, then the gallery labels aren't responsable (the label is cut off):

Thanks and regards!
