I'm trying to display the ToggleButtons vertically (buttons stacked on top of each other) in Mendix. I'm doing this using custom styling only, without modifying the widget’s source code. I’ve already tried: Applying flexDirection: "column" in various places (e.g., container, button). Using Mendix’s theme files like custom-classes.js, input-overrides.js, and built-in flex helpers (flexColumn). The result: The background color and other basic styles apply correctly. But flexDirection: "column" has no effect—the buttons are still rendered horizontally. After inspecting the widget, I’ve found that it uses the SegmentedControlTab component internally. That component wraps the buttons inside a hardcoded View with flexDirection: "row" by default. This layout is not exposed or overridable via Mendix's styling system. Any assistance from styling experts would be greatly appreciated.
