less elements than the grid size

[taixes]

If I have in my carousel less elements than the grid size (example: I have 2 elements and the size is 3):

• I'd like the current elements to fill the whole carousel, as if the size were 2. I tried to do it updating the variable this.carouselTileConfig.grid = { new values } in ngOnInit but it didn't work at all. Even resetting the carousel, the changes don't take effect.
• I'd like an option to make the arrows disappear (similar to hideOnSingleSlide: true, but with the arrows). I can get it doing [style.opacity]="myCarousel.isFirst ? 0:1", in NguCarouselPrev, but then it also disappears when I have more elements and I'm at the first slide.

Thank you!
