Ion-scroll

Hi,
I have a ion-content with scroll=“false” that has two container with lists. the first one should not scroll and it must be fix but the second container must scroll for its items (the green items).
Second container has 8 items but i can not catch item 8 !!
There is an topic in Ion-list inside card that is similar to my problem but i can not fix my problem.
what should i do ?
my codepen is: http://codepen.io/mohamadreza_gs/pen/eNbWgW
Are there any way that when mobile screen was very small, first container scroll too?
thanks for your attention.

ion-scroll needs a fixed height to calculate the scroll-container correctly.
So set the height of the ion-scroll to a fixed value… it will be scroll like it should.

If you need a generic solution you could create a directive to calculate the correct height on the fly.
