Hi,

May I know which demo are you working on?

THanks



Hi,

Demo1 angular theme.

Thanks



Apologies for the delay, we have missed your reply, and thank you for your patience. To address your request, please follow these instructions:

In the file /demo1/src/app/_metronic/layout/layout.component.ts, add the following code within the ngOnInit() function:

ngOnInit() {
document.body.setAttribute("data-kt-app-sidebar-minimize", "on");
}


This code will set the attribute data-kt-app-sidebar-minimize to 'on' for the body element. If you have any further questions or concerns, feel free to ask.



Thanks for your reply. But this was not my query.
When I click a menu, it is okay:
https://ibb.co/qn2Z3G7
But when I reload the page: menu is minimized:
https://ibb.co/kmkv1b0

Please give a solution



Hi,

You can use the routerLinkActive directive to detect the active menu. This helps in maintaining the correct state of the menu, whether it should be minimized or not.

Here's how you can modify your code:

In the parent menu, add the routerLinkActive directive with a class that represents the active state:

<div class="menu-item menu-accordion" data-kt-menu-trigger="click" routerLinkActive="here">
<!-- Your menu content here -->
</div>

In the child menu, you can similarly use the routerLinkActive directive to detect the active state and apply a class (e.g., "active") accordingly:

<a class="menu-link without-sub" routerLinkActive="active" routerLink="/admin/subjectentry">
<!-- Your menu link content here -->
</a>

Make sure you have the corresponding styles for the "here" and "active" classes in your CSS to define the appearance of the active menu state.

This way, the menu will maintain its minimized or expanded state based on the active route, preventing it from being minimized on refresh.

We already have routerlinkactive

but when we click the menu, it appears ok
https://ibb.co/Z1mtCpN

when we refresh the page:

https://ibb.co/n831BX6

menu is minimized.

But when we expand the menu it shows menu active
https://ibb.co/ZG3w9Y6

Please give us the solution.

For your convenience, I paste the html and ts code with json array instead of database.

Thanks.

Hi,

It seems like you're facing an issue with maintaining the expanded state of your menu when the page is refreshed. One way to address this is to determine the active menu item based on the current URL. You can achieve this by comparing the current URL with the URLs of the menu items.

Here's an example of how you can modify your SidebarMenuComponent to detect the active menu item using the current URL:

Update SidebarMenuComponent:


// sidebar-menu.component.ts
import { ChangeDetectorRef, Component, Inject, OnDestroy, OnInit } from "@angular/core";
import { DOCUMENT } from "@angular/common";
import { Router, NavigationEnd } from "@angular/router"; // Import Router and NavigationEnd
import { Subscription } from "rxjs";
import { filter } from "rxjs/operators"; // Import filter operator
import { MenuService } from "src/app/services/menu.service";

interface DataItem {
MENU_ITEM_ID: number;
PARENT_MENU_ITEM_ID: number;
MENU_DESCRIPTION: string;
MENU_URL: string;
}

@Component({
selector: "app-sidebar-menu",
templateUrl: "./sidebar-menu.component.html",
styleUrls: ["./sidebar-menu.component.scss"],
})
export class SidebarMenuComponent implements OnInit, OnDestroy {
subscriptions: Subscription[] = [];
ParentMenuList: any;
child1List: any;
child2List: any;
currentUrl: string; // Store the current URL

DBmenuList: DataItem[] = [
// ... (existing menu items)
];

constructor(
private cdr: ChangeDetectorRef,
private menuService: MenuService,
private router: Router, // Inject the router
@Inject(DOCUMENT) document: Document
) {
document.getElementById("kt_app_sidebar_menu")?.click();

// Subscribe to NavigationEnd events to update the active menu item on route changes
this.subscriptions.push(
this.router.events
.pipe(filter((event) => event instanceof NavigationEnd))
.subscribe((event: NavigationEnd) => {
this.currentUrl = event.urlAfterRedirects;
this.setActiveMenu();
})
);
}

ngOnInit(): void {
this.getDBmenuList();
console.log("menuList", this.DBmenuList);

// Get the current URL on component initialization
this.currentUrl = this.router.url;
this.setActiveMenu();
}

getDBmenuList() {
this.ParentMenuList = this.DBmenuList.filter((w) => w.PARENT_MENU_ITEM_ID == 0);
}

getChild1Menu(MenuItemId: number) {
this.child1List = this.DBmenuList.filter((w) => w.PARENT_MENU_ITEM_ID == MenuItemId);
}

getChild2Menu(MenuItemId: number) {
this.child2List = this.DBmenuList.filter((w) => w.PARENT_MENU_ITEM_ID == MenuItemId);
}

setActiveMenu() {
// Loop through menu items and set the active property based on the current URL
this.DBmenuList.forEach((item) => {
item.active = this.currentUrl.includes(item.MENU_URL);
});
}

ngOnDestroy() {
this.subscriptions.forEach((sb) => sb.unsubscribe());
}
}


Update sidebar-menu.component.html:


<!-- ... (existing code) -->

<div class="menu-item menu-accordion" data-kt-menu-trigger="click" (click)="expandMenu()" [ngClass]="{ "here": item.active }">
<!-- ... (existing code) -->
</div>

<!-- ... (existing code) -->


In this modification:

- We use the Router service to subscribe to NavigationEnd events, which occur when the route changes.
- The setActiveMenu method is called on initialization and every time the route changes. It loops through the menu items and sets the active property based on whether the current URL includes the menu item's URL.
- The ngClass directive in the HTML is used to conditionally apply the 'here' class to the menu item if it is active.

Please adjust the code according to your specific needs and styling conventions. This approach should help maintain the expanded state of the menu based on the current URL.



Hi,

You give html click event (click)="expandMenu()" but did not give typescript code.

You did not give routerLinkActive="here"

if it is okay

<div class="menu-item menu-accordion" data-kt-menu-trigger="click"
(click)="expandMenu()" [ngClass]="{'here': item.active }">


Please give me expandMenu() typescript method

Thanks
