Align Controls

Hello,
I’m trying to align my controls.
I’m expecting something like this:

|DropDown| Button| --blank-- | DIV x,y coordinates |

Unfortunately, I’m unable to align the x,y coordinates to the right side of the row. In addition, the “Show Start Points” button is stuck on the top. I only managed to set it on the same height as the DropDown by setting the margin top.

Is there a better way to get the dropdown, button and DIV on the same height?
How can I align the DIV to the right?

With my current code I got the following output:

    TOP_CONTROL_MARGIN=margin=(25, 0, 0, 0)
    def create_dropdown(self):
        # Extract subject names for the dropdown
        subject_names = [subject.subject_id for subject in self.gradingSubjects]
        self.dropdown_subjects = Select(title="Select Subject:", value=subject_names[0], options=subject_names)
        self.current_subject = self.gradingSubjects[0]  # Set the initial subject
        self.dropdown_subjects.on_change("value", self.on_dropdown_subject_change)
        self.load_subject_image(self.current_subject)  # Load the initial subject's image

    def create_show_start_points_button(self):
        # Create a button to toggle start points
        self.start_show_points_button = Button(label="Show Start Points", button_type="default",margin=BokehPlot.TOP_CONTROL_MARGIN)
        self.start_show_points_button.on_click(self.toggle_show_start_points)

    def layout(self):

        # Ensure the dropdown, button, and figure are created
        if not self.dropdown_subjects:
            self.create_dropdown()
        if not self.start_show_points_button:
            self.create_show_start_points_button()

        # Create a Div to display mouse position
        self.mouse_position_div = Div(text="Mouse Position: x=0, y=0", margin=BokehPlot.TOP_CONTROL_MARGIN)

        # Add a callback to update the Div with the current mouse position
        def update_mouse_position(event):
            self.mouse_position_div.text = f"x={event.x:.2f}, y={event.y:.2f}"

        self.figure.on_event('mousemove', update_mouse_position)

        # Arrange the dropdown, button, and Div in the same row
        controls = row(
            self.dropdown_subjects, 
            self.start_show_points_button, 
            self.mouse_position_div, 
            sizing_mode="fixed",
        )
        return column(controls, self.figure, sizing_mode="stretch_both")


Any help appreciated! Thanks
