New setting to make all menu apps collapsable

[Zerotask]

Is it a third party application feature request?

No

Describe your feature request

We have many apps and models which makes our sidebar huge. Therefore we simply want to make all apps collapsable and collapsed by default, but we don't want to define every single app and model in the setting. Therefore we'd like to have a new setting added to unfold:

"SIDEBAR": {
        "collapsible_menu": False,  # Make all applications collapsible. Default: False
}

Perhaps there could be a 2nd setting to define if it's collapsed or not be default
