Actual Results

The suggestions in the search field are inaccessible for screen reader users and cannot be navigated using the "Down Arrow" key when the screen reader's virtual cursor is switched on.
Users relying on assistive technologies are unable to interact with these suggestions effectively.

Expected Results

All list entries and menu items should be navigable and selectable using the screen reader users should be able to access and interact with these elements without switching off the virtual cursor.
Submenus should operate consistently throughout the application.
