Ionicslidebox with different slide sizes


newly question, sorry.

I need to build a slidebox that has 50% of screen height.
but when swiping the first slide the right, it displays another view (or page, or screen, or any container but of 100% of vertical screen height)
I looked for a way to specify on-swipe-right slide by slide but it does not make sense to me as this is embedded in the slide box template.

any idea or hint, thanks a lot.
