Initial size based on content?

[dkozar]

Hi,

I'd like to use the split pane in horizontal mode (first panel above, second one below).

When the split pane is mounted, I'd like to determine the top/bottom section sizes based on their contents (so there are no individual scrollbars apart from the page scrollbar).

Is this possible to do?

Thanks!

It's possible.

• React.useRef to get a ref which you associate with your element you want to measure.
• React.useEffect to run some code after your component renders for the first time
• In the useEffect, read the properties of the HTML element e.g. its clientHeight
• Use that height, now that you know it, to set/reset the size of the pane
• And maybe [once, setOnce = React.useState(false) which you use to ensure that you do the above only once/initially
