Good!

I keep fighting with the theme editor xD

This time I can't understand why a sub-widget that I left marked as dynamic keeps appearing on the screen. I have a theme that I did a few months ago in which it works and I have configured it in the same way, but I cannot get that data that is not visible disappear (Including the background image)

I share an image

You should generally not use "Dynamic" for items in a Ticker. The ticker decides by itself how many items to show, it should only show items for drivers in the session (or less).

I think you can use Dynamic for a static ticker, but not for a paging ticker. I think if you simply uncheck Dynamic in your template subwidget, your ticker will show only 7 items.

For some reason if I use a ticker with the paging format the theme slows down and I can't use it.

That is why I use a ticker in static format but even putting the sub-widget in dynamic, the background image continues to appear.
