Container component's height expand to full height of the page

I am going to stretch the container height to the full height of the screen, but it's only fit to content.

I'd like to know how to expand it in height 100%

Try setting the height to fixed and drag it down I don't believe, unless you want to use Custom CSS, this isn't done by default in Retool

Hello @Green_Earth!

There is a feature we recently launched that adds support for this called "Expand content to fit":

It's an option on Frames and Containers when there is only single child component. When enabled, it will expand the child to fill all available space. This is equivalent to the viewport (screen) when enabled on the Main or Sidebar frame.

It looks like you're creating a navigation sidebar, in which case I would recommend using the Sidebar frame!

Happy building!
