Ability to trigger action on change of tab

[michaelblight]

I would like to use a tabbed card on a mobile device but not on a tablet or larger, without having to code everything twice. I can use the sections layout and control visibility based on screen size. On mobile the tab card displays, along with one other section; on tablet the tab card does not display, but all other sections do. However, changing tabs does not trigger anything that can cause the visibility to change.

If (for example) I could specify an action on change of tab, I could set an input-number to the current tab number, and then use this in visibility. I would also need to specify "no" card to be displayed under the tab (eg: card: type: none), as the content is in separate sections to the tab card.
