Menu Custom Dropdown opens a panel built from child elements inside Menu Builder.
Build the Panel
Add Menu Custom Dropdown directly inside Menu Builder.
Set Content > Content > Text for its toggle label, then add the panel's child elements.
Arrange children under Design > Layout and configure background, padding, borders, and width under Wrapper.
Match Advanced > Disable Desktop Styles At to the parent menu's mobile breakpoint, then save.
Text labels the toggle; it does not populate the panel. The optional Link gives the toggle a destination, but this conflicts with opening the panel on mobile. Put destination links inside the panel instead.
Child elements retain their own design controls. Check their widths if they overflow, and their styles if they differ from the parent menu.
Full editor with Menu Custom Dropdown expanded in Structure, its child image and links visible, and the Layout control outlined with a yellow-highlighted pointer
Controls
Responsive varies by breakpoint; Hover has a hover value; Shared applies across both. In conditions, = means “is” and ≠ means “is not.”
