Hi,

That’s not doable with Java. It might be possible with something like CSS
transform: rotate(-90deg)
, but it’s probably going to need other adjustments as well.

Any ideas how I can do it anyway? Because I really need It.

Did you try the CSS transform?

The .CSS file have 12400 rows. I cant find that … :confused: But there is it. → https://pastebin.com/CxSDigiq . Can you find the row where I must the write that transform code? Thanks !

Put it in your Theme instead. See
https://vaadin.com/docs/-/part/framework/themes/themes-creating.html
for details.
