Open dropdown menu

When you select a Dropdown menu element on the canvas, the editor automatically opens the menu to display all its sub-items, as if they were already expanded for a visitor.

When the menu closes

The menu stays open as long as it is selected. As soon as you click elsewhere on the canvas (on another block or in empty space), it automatically closes and resumes its normal visitor behavior.

This interaction is fully automatic: there's no button to enable. Select the menu, edit what you want from the side panel, then click elsewhere to see the visitor rendering.

Why this auto-opening

Without it, you would only see the dropdown menu's button and it would be impossible to judge the formatting of sub-items (texts, descriptions, spacing). By forcing the opening during edit, the editor shows you live the result of every change made in the side panel.
