[Enhancement]: Control modelSelect in the content area and in the sidebar independently

[dhaussener]

What features would you like to see added?

When creating a menu with modelSpecs (e.g. models with descriptions), the endpoint and the model menu in the content area are no longer required. However, if you hide the menus, the list of all agents in the sidebar also disappears. If you set interface: modelSelect = false the individual agents can no longer be selected at all.

Proposed Solution:

It would be great if the model menu in the content area could be hidden independently of the sidebar.
