Panel with fixed size

[ronildo]

Is there a way to have two panels so that the left side doesn't change if the window size changes

For example on Shadcn website, if you remove the container class from the website, it expands to the whole screen.
From the two images you can see that the left sidebar changed because the window size changed.

The only way to lock a panel's size is set min and max size to the same value.

The primary purpose of this library is resizable panels though, so I'm not really sure why you'd want to do that. :)
