Making vertical ScrollAreas inside a horizontal layout use available space

[exoticorn]

I have multiple columns containing a scroll-able custom widget. I'd like this ScrollArea to take up all remaining vertical space but they seem to be stuck at some minimum height. I created a minimal test:

struct TestApp;

impl epi::App for TestApp {
    fn name(&self) -> &str {
        "TestApp"
    }

    fn update(&mut self, ctx: &egui::Context, _frame: &epi::Frame) {
        egui::CentralPanel::default().show(ctx, |ui| {
            ui.horizontal(|ui| {
                egui::ScrollArea::vertical()
                    .id_source("first")
                    .show(ui, |ui| {
                        ui.add_sized([100., 200.], egui::Button::new("First"));
                    });

                egui::ScrollArea::vertical()
                    .id_source("second")
                    .show(ui, |ui| {
                        ui.add_sized([100., 200.], egui::Button::new("Second"));
                    });
            });
        });
    }
}

I tried ui.set_height(ui.available_height()) inside the ui::horizontal which didn't change anything.

Is this a limitation inside a horizontal layout? I guess I could layout my columns manually to better control the sizes.

Of course, right after posting the question I found the answer myself: Just replace ui::horizontal(...) with

ui.with_layout(egui::Layout::left_to_right().with_cross_justify(true), |ui| {
