collapsable vertical meg menu for elementor

I need a collapsable vertical menu with icons. One item inside the vertical menu also needs to show a mega menu.
example of vertical menu: https://themes.themesbrand.com/velzon/angular/default/analytics
example of mega menu: https://jsn.ijj.mybluehostin.me/home-1/

I need this done within 2-3 hours starting now.
