Div scroll horizontally over another fixed div

Hi, I’m fresh to webflow and have a slight problem over a page I’m trying to make. In short I want to make a dashboard, the dashboard part stays with fixed value on the left while the other div placed next to it. While I’m able to have the dashboard stays while scrolling vertically the div next to it that should only scrolls vertically as well messed up that let the page scrolls horizontally. Can someone with more experiences enlighten me with suggestion or answers ?
