I like how Tabs scroll responsively, knowing on mobile devices to head to the beginning, and I like how intuitive the + key is. However, if after opening a lengthy tab, the reader sees that the content is not relevant, I can’t find any way to close the tab, requiring a lengthy scroll.
Shouldn’t there be a “-” sign, to go along with the “+” sign? Perhaps that option is there and I’m just missing it?
I believe you are referring to the accordion module? There is a minus symbol and should be present for you too. Would you mind sending a link to the site so I can take a look?
