Change Menu behaviour on viewport change

**Is your feature request related to a problem? Please describe.**
Currently, when the screen size changes, the menu automatically closes. This is problematic in scenarios where the menu should remain open after, for example, an orientation change or when it needs to coexist with an inner text field that triggers the software keyboard to open.

**Describe the solution you'd like**
Provide a way to customize this behavior, e.g., via a new component prop. It could accept two options: one for the default (current) behavior, and another to keep the menu open and reposition it after a viewport change.

Start by locating the menu component and the existing viewport-change behavior. Read the related component tests, if present, to understand how closing and repositioning are currently verified. Done means the behavior can be selected through a component prop and remains covered for both the default closing behavior and the keep-open behavior.
