Describe the bug

Hello,

in flet 0.28.3 my dropdowns are correct expanded to all available space using expand=True.
Unfortunately this doesnt work anymore in flet 0.80.1.

Its possible to set a width, but at this point i cant access page.width in my app, the other problem with setting a specific width is that even menu_width key is set the menu goes over the whole page.

I tried also to place the dropdown in a ft.ResponsiveRow and gave col={"sm":12} but that also didnt work.
I think expand=True should work and its maybe a bug that it do nothing on dropdown, i dont know..

Is there any way to let a dropdown use all available space in a page / column / row / container without using the width key ?

Thanks in advanced

Code sample

Code

import flet as ft

def main(page: ft.Page):
    page.spacing = 20
    page.padding = 20

    severity_dropdown =  ft.Dropdown(
                    
                        label="Severity",
                        leading_icon=ft.Icons.WARNING_ROUNDED,

                                ),
                                
                            ),
                            ft.DropdownOption(

                            ),
                            ft.DropdownOption(
                                key="danger",
                                content=ft.Text(
                                    value="Danger (Red)",
                                    color=ft.Colors.RED_400
                                ),
                               
                            ),

                        ],
                        expand=True,

As from Flet v0.80.4, you can now use expand=True to do this.
