React MUI - Consistent Tab Content Height

Question

I understand that ideally should be placed at the top of the page. However, Assume they are place in the middle of the page. When changing from a tab with a lot of content, to a tab with little content, the scrollable area disappears. Is there anyway to preserve the white space?

Here is a code sandbox example.

Step 1 scroll down to tabs.

Step 2 scroll down tab 1 content( leave tabs visible)

Step 3 click tab 2 (Mouse no longer is hovering over tabs because vertical scroll content vanishes)

Edit: I am able to change my root div min height to whatever I need hard-coded. I feel like this hacky though and not dynamic to the tallest tab

Answer 1

You can set minHeight style to tab2 and tab3 to be the height of tab1 using useRef

const tabRef = React.useRef<HTMLDivElement>(null)
const [tabHeight, setTabHeight] = React.useState(0);
React.useEffect(() => {
    setTabHeight(tabRef.current.clientHeight)
}, [tabRef]);


<TabPanel value="1" ref={tabRef}></TabPanel>
<TabPanel value="2" sx={{ minHeight: tabHeight }}></TabPanel>
<TabPanel value="3" sx={{ minHeight: tabHeight }}></TabPanel>
