I don’t know CSS, will it be complicate? Will it bring any downsides?
Good suggestion, but it’s a step more, and I don’t want the user to be able to click and open another list (that I have to set up, and that is not fully customizable)
Another list will only open if they click the “see all” link. That link will only be shown if you have chosen to limit the number of items displayed AND the number in the list exceeds that.
