I was wondering if there were any suggestions on how to go about this. I could do this with a custom component from some prebuilt react components (I'm assuming MUI is compatible with Retool) or I could just use a horizontal list component and some custom javascript and CSS.
Its such a common pattern I would like not to reinvent the wheel. . .
You can definitely use a horizontal list view. The container component has a "hovered" property that you can use to then dynamically select the main image (and also give effects to the container's margin):
