Hi everybody

I follow this guide to create a scrollable box with different buttons:

> **[A new, community-hosted Unreal Engine Wiki](https://forums.unrealengine.com/t/a-new-community-hosted-unreal-engine-wiki/141494)**
>
> After over a year in maintenance mode, the official Unreal Engine Wiki is now permanently offline. These resources now live on a new community-run Unreal Engine Community Wiki — ue4community.wiki! You will be able to find content from the official...

And now I’m blocked. I want my buttons to be interactible with an actor. I’d like to change material of an actor through the ScrollBox.

Here’s what an actor do at the moment:

And I’d like to do the same for all the new button I created through the guide

Can someone help me?  
Thank you all

Lorenzo

you need create a sequence when the actor click on the button set material.  
asssin on clic or on pressed button.
