I think self-stretch should override height inside the respective div but it's not happening.
https://codepen.io/hamdan85/pen/jRBvNg
Items dont have their height overrided to full-height
Two cols inside a row with items-stretch should have its children divs stretched for full height,
Two a col with self-stretch should have its children divs stretched for full height
full-height class should override a QInput (type textarea) to have a full height
It's exemplified in codepen
I asked @Hamdan85 to file this issue because even though it could be solved by adding a rows="8" prop to
This is not how CSS works. self-stretch does not apply to the content of an Element but to the Element (that it is applied to) itself. Which works correctly (highlighted below).

@rstoenescu as I said in the description of the problem, I tried to make it be stretched in many ways... Qinput also didnt responded to full-height class...
I ask you to see the bigger picture in the problem because QInput didnt had its height override in none of the exposed scenarios.
EG:
I also tried flex items-stretch and full-height classes, and also tried self-stretch applied in QInput class
Your reported problem: "self-stretch is not overriding height"
As I've shown you, this is not the case. You apply "self-stretch" on the QInput's parent (even though you don't need it, but regardless..) and the bug report says self-stretch does not override height -- in your case, it doesn't even need to, because it already stretches to full available height due to how flexbox works.
A correct ticket should sound like "How to make QInput textarea occupy full height of parent", not reporting a bug in self-stretch. Regardless, here is your answer: https://codepen.io/rstoenescu/pen/YMZMqL?editors=1100
Thanks for the clarification Razvan. @Hamdan85 - my feeling here is that you are trying to change material design spec on the inputs...Had I understood your "bigger picture" issue I wouldn't have encouraged the creation of the issue.
ok.. understood... thank you guys ;)

It seems that your solution it still not working for some reason on the go... but Ill use the one @nothingismagick proposed.
Thanks

You using <style scoped> in your Vue file?
for the sake of test, i tried inside a scoped style and inside a non scoped... the result was the same.
but @rstoenescu, im just reporting trying to help. I have used the @nothingismagick 's solution and it's working fine.
