In your Angular project, you can easily add menus to the sidebar by modifying the MENUITEMS array in the nav.service.ts (src\app\shared\services\nav.service.ts) file. The sidebar will dynamically display the menus based on the contents of this array.

Steps:

1 .Open nav.service.ts File:

Open the nav.service.ts (src\app\shared\services\nav.service.ts) file in your Angular project. This file contains the MENUITEMS array that defines the menus to be displayed in the sidebar.

To add the parent Menu Items:

Inside the MENUITEMS array, you can add your menu items using the following format:

{
    title: 'Your Menu Title',
    selected: false,
    icon: 'icon-name',
    type: 'link', // or 'sub', 'mega-menu', 'external', 'empty'
    path: '/path-to-route', // Specify the route path for link type
    active: false,
    badgeClass: 'badge-class', // (optional) Add a badge to the menu item
    badgeValue: 'Badge Text', // (optional) Text to display in the badge
 }

To add the children Menu Items:

Inside the MENUITEMS array, you can add your menu items using the following format:

{
    title: 'Your Menu Title',
    selected: false,
    icon: 'icon-name',
    type: 'link', // or 'sub', 'mega-menu', 'external', 'empty'
    active: false,
    badgeClass: 'badge-class', // (optional) Add a badge to the menu item
    badgeValue: 'Badge Text', // (optional) Text to display in the badge
    children: [
     // (optional) Define child items for sub-menu or mega-menu type
     {
       path: '/child-path',
       title: 'Child Menu Title',
       type: 'link',
       selected: false,
     },
     // Add more child items if needed
   ],
 }

• title: The display name of the menu.
• selected: Set to true if this menu is currently selected.
• icon: The icon to display next to the menu.
• type: Specify the type of the menu item (link, sub, mega-menu, external, empty).
• path: Specify the route path for link type menu.
• Menusub: Set to true for sub-menu or mega-menu types.

• badgeClass (optional): CSS class for the badge.
• badgeValue (optional): Text to display in the badge.
• children: Define an array of child menu items for sub-menu or mega-menu type.

3 . Save the Changes:

After adding your menu items, save the changes made to the nav.service.ts (src\app\shared\services\nav.service.ts) file.

4 . View Sidebar Changes:

he sidebar will now automatically display the added menu items based on the modifications you made in the MENUITEMS array.
