I am unable to access all the buttons parented to the scrolling frame. I want to make it freely be able to do so. Any UI elements I should use?

I’m currently using a combination of a scrolling frame and a UI grid layout. Help?

Never mind this is what I neede Is there any way to make a scrolling frame longer as it gets more items? - #3 by Elttob
