    Hello, like the title says I'm currently trying to find a updated a free way to instantiate a prefab when scrolling a scrollview. I have a menu with like 100 items and instantiate 100 of them is really heavy and laggy so I was wondering how to instantiate like 10 objects and reuse them while scrolling up/down

    Thanks.

    Wrong Forum to ask. You want to ask the UI forum for this sort of thing. My guess is you'll need custom version of the scroll view, but that's only a guess.

    Wrong forum like already said.

    Did you actually check asset store? IIRC there are free solutions for scrollrect that recycle items.

    It is not trivial to do IMO so try those first (I've created such script once, had all kinds of issues)?

    I just don't want to mess the script by adding/removing stuff, the script I made changes texts and images when populating the canvas
