Container

A vertical box for grouping components. Column is an alias of Container.

with sc.Container(border=True, border_title='Settings', height=320):
    sc.Checkbox('Enable caching')
    sc.NumberInput('Workers', value=4)

Argument	Type	Meaning
`width`	size keyword	Width
`weight`	`float`	Flex-grow ratio inside a `Row`
`border`	`bool`	Draw a frame
`border_title`	`str \| Property`	Title drawn in the top border
`height`	size keyword	Fixed height; content scrolls
`animated`	`bool`	Animate the height when `visible` flips
`visible`	`bool \| Property`	Default `True`

Properties: border_title, visible.

Scrolling

A fixed height caps the box and makes it scroll:

with sc.Container(height=240):
    for line in lines:
        sc.Text(line)

max_height has the same effect. min_height does not.

height='stretch' makes the container fill the parent’s height. Inside a Row, it spans the row’s tallest sibling:

with sc.Row():
    with sc.Container(height='stretch'):
        sc.Text('Left')
    with sc.Container(height='stretch'):
        sc.Text('Right')

visible controls whether the container is rendered. animated=True transitions the height instead of making it pop:

with sc.Container(visible=state.show_advanced, animated=True):
    sc.Text('Advanced options')

The container stays in the tree either way, so a later patch can bring it back.

border_title is only honored with border=True. It is drawn inline in the frame, the way a <legend> sits in a fieldset.
