pub fn displayContainer(src: std.builtin.SourceLocation, field_name: ?[]const u8, default_expanded: bool) ?*dvui.BoxWidget {
    var vbox: ?*dvui.BoxWidget = null;
    if (field_name == null or dvui.expander(
        src,
        field_name.?,
        .{ .default_expanded = default_expanded },
        .{ .expand = .horizontal },
    )) {
        // Use src again in case exoander is not created.
        vbox = dvui.box(src, .{ .dir = .vertical }, .{
            .expand = .horizontal,
            .border = if (field_name != null) .{ .x = 1 } else null,
            .background = true,
            .margin = if (field_name != null) .{ .x = 12 } else null,
            .id_extra = 1,
        });
