Are there any variants to set popup height by content ? As I see, for that, we can use popupSettings.height for that, but in this case I have to calculate height manually.

Hello,

By setting popupSettings.height to 'auto', the browser will calculate it for you. Here is an example - https://stackblitz.com/edit/react-xa5jqs?file=app/main.jsx.

Still isn't what I'm looking for - I need something like maxHeight

I'm trying to build filtering and when It contains many elements,-  It should show scroll, otherwise should work like height auto.

Maybe smth like this
popupSettings.height = items.length > 5  ? '100' : 'auto' ?
Would It work properly

No, this approach doesn't work.

Hello, Sergey,

Thank you for the clarification.

The height property actually sets max-height CSS rules instead of height:

This means, that setting it will show scrolling when there are many items and automatically remove it when there are less items.
