Show current page on menu

[FlorianJacta]

Description

The menu needs to show the proper current page when not navigating directly through the menu.

A code to replicate the issue:

from taipy import Gui, navigate
import taipy.gui.builder as tgb

def menu_option_selected(state, action, info):
    page = info["args"][0]
    navigate(state, to=page)

with tgb.Page() as root_page:
    tgb.menu(label="Menu",
            lov=[('home', 'Page 1'), ('about', 'Page 2')],
            on_action=menu_option_selected)
    tgb.text("# Multi-page application", mode="md")

with tgb.Page() as home_page:
    tgb.text("# Home", mode="md")

with tgb.Page() as about_page:
    tgb.text("# About", mode="md")

pages = {
    "/": root_page,
    "home": home_page,
    "about": about_page
}

Gui(pages=pages).run()

Here, if the user manually enters the URL or page name, the menu will not show which page we are on.

This is an expected behavior, as the menu should not normally be used for navigation but for actions (like buttons). We could have a mode for the menu to be used in the context of navigation so that the menu recognizes on which we are.

The menu should be updated depending on the actual current page I am in.

@NILAY1556 I haven’t started working on this issue yet as I haven’t been assigned to it yet. I have no problem collaborating with you on the issue. @FlorianJacta @FredLL-Avaiga is it possible for two contributors to be assigned on an issue?

[FlorianJacta]

We can do with two contributors.

@namnguyen20999 is also working on it inside of our R&D.

I don't think there's enough meat on this issue for more than one especially if it is @namnguyen20999 ;-)
