We will do this step by step, the goal here is to learn how to configure the Angular Router by example and learn how to implement some of the very common routing scenarios that you will likely find during your everyday development. We want to start by implementing the top menu, which will always be visible no matter where we navigate inside the application. For that we are going to add the top menu at the level of the root component of the application:.
If the menu is too big then a good alternative is to put it in a separate top-menu. Notice the routerLink directives, linking to homeabout and courses. Also notice the router-outlet tag: this means the main content of the page below the top menu will be placed there.
Also notice that there is no side navigation bar at this stage. The side navigation should only be visible if we click on Courses. Let's now write the router configuration for the top menu. As we can see, the homeabout and courses Url paths currently map to only one component. This is a good start, we have defined the home page, handled invalid URLs and added a couple of common navigation items.
As we can see, the main content of the page everything below the top menu was applied in place of the router outlet. But this Courses page will also have other internal routing scenarios as we will see further. In order to create the navigation side menu, we would like the CoursesComponent to contain a couple of router outlets itself:.
To implement this scenario we need to first start by going over Child Routes. We can learn more about Child Routes in this previous postor you might want to check this video:. Let's have a look at the CoursesComponent template, to see how we have implemented it:.
Notice that there are a couple of router-outlet elements inside the courses component, which is itself being injected in place of a router outlet! This is sometimes referred to as the "nested" route scenario. We will go over the side menu outlet in a moment, but right now we want to configure the router to include the course category cards component in place of the unnamed router outlet.
In order to display the courses component and the course categories card inside it, we need the following router configuration:. But how do we display the side menu? For that, we are going to need what is sometimes referred to an auxiliary route.
Auxiliary route is a common term to describe this scenario where we have multiple portions of the screen whose content is dependent upon the value of the url. In terms of router configuration, this corresponds to a route with a non-default outlet name.
If you want to learn more on auxiliary routes before continuing, have a look at either this previous postor this video on auxiliary routes:. The side menu will be displayed in the sidemenu router outlet, and we would want the content of the side menu links to be dynamic and depend on the URL.
For example, when first viewing the Courses section we would like it to contain a list of Course Categories like in the screenshot above. But when you navigate inside a course category, we might want to display for example a list of course sub-categories. Notice that this is just a skeleton implementation of the side menu. We would need to inject a service and get the data, or even better we could load the data before creating the component using a Router Resolver.
We can see here that the side menu component gets notified whenever a change in the URL occurs, which is the essential part of making the side menu adaptable to the URL content.
We can start seeing here a pattern: a large variety of many of the routing scenarios that we typically want to implement can be configured by using only a few configuration notions: routes, outlets, child routes. Let's see a further example of this, where we will go one navigation level deeper in the application routing! Let's say that now if we are in courses and click for example in Developmentwe would like the following to occur:. This could be for example a list of sub-categories.
So in this scenario, we will have two different sections of the page that will react separately to the URL change: the side menu and the main body of the Courses page. Now let's say that the user clicks on Development. We want a new CoursesCategoryComponent component in this case to be displayed in the main body of the Courses page.If you want to learn about Angular Material Dialogs, Tooltips and SnackBars you should also check out the second part.
The following steps assume that you have already a new Angular 4 project set up and included the Angular Material library. Add the following import statement:. Open file menudemo. The top level element is a md-card element which contains two child elements: md-card-title and md-card-content.
The most important code excerpt can be found within the md-card-content element. First a button is included. The button is displayed in material design by attaching the md-raised-butto n directive to the element.
If the user clicks on this button a menu should be displayed. This is achieved by using the mdMenuTriggerFor directive and assigning a string value. This value must be the name of the template variable of the menu which should be displayed by clicking on the button. Next the menu is created by using the md-menu element.
The menu consists of three menu items. Each item is added to the template by using a button element and adding the md-menu-item directive to the button element. The md-icon element is used to display an icon next to the menu item text. To include MenuDemoComponent in the output of our application you need to add the app-menudemo element in app.
Clicking on the Open Menu button opens the menu:. This means that a md-menu-item element opens another sub-menu.
Now you need to add the definition of subMenu by included another md-menu element in the template code:. If you now click on the Settings item in the root menu the sub-menu opens up:. Sidenav is part of the Angular Material library and makes it possible to display a panel next or beside some primary content.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

The menu docs only include a nested menu example using static HTML. This is a common use case for building application menus, especially for business applications.
Dynamic Menu Generation With Web API And Angular
There is an example of creating md-menu's dynamically here but it doesn't demonstrate nesting. I've finally got something working on the latest snapshots. It's not possible in beta. I'm working on distilling it down to a simple docs-ready example atm. Splaktar I'm interested to see what you find I just filed because it's not currently possible to use a recursive ng-template for creating a nested menu. Any help would be more than welcome. I will publish what I got working next week.Hd crt tv
It is quite a different approach to what cpboyd details in Splaktar just awesome man Question: If a need to bind the actual route, it must be hard coded on rounting.
Mayocampo Glad that it could help, thanks for the feedback :. Yeah, I didn't hook up the routing to be generated dynamically. That's another topic that I haven't dug into just yet : So yes, for now I just make sure that the app-routing. I'll be presenting on this at AngularMix on Thursday. Then I'll share my slides and some more examples including a dynamic SideNav menu. Hopefully I'll have time to put together the docs as well, but that will have to wait until later in November most likely.

The solution has a common pattern you can follow using built in angular router and some custom route inspection code.Angular 6 - Adding Bootstrap 4 Dropdown Menu in Angular Application and ng-bootstrap
Some simple projects may be fine just adding a few components to the AppModule and have a completed app, but business scale apps will include multiple application areas. They may be connected by a common app menu, or by accessing functions within each component. This application will consist of 3 main page components. Each page component will be contained within a module with routing. The navigation component included at the top of each page component will read the routing to build the menu.
You can also add other menu items, such as for linking outside the SPA into another umbrella site. See the previous article if you are working in a Visual Studio project. This article will work for anyone in other editors as well.
Open the command prompt and ensure npm and the cli commands are available in your path. I am using the current latest version of each, NPM version 3. Your console will show your full path. Its easy to create a new component and module following the style guide best practices, plus the command hooks up the newly created components to the right module.
Start by creating a page component module. Now that we have a module for this application area, lets create a component for the page. This command added the newly generated component to the trip module. It does this by traversing up the folder tree to the nearest folder containing a module, then adds itself to that module. The folder you run CLI commands in matters. Our page components are all going to render a menu for app routes so the user can navigate between app components.
Well, it is easy to do just that. See the prior article for how we arrived at this point. The output tells us that much, but what can we do about it? The warning gave us a clue, lets edit the AppModule and provide the service. Why the AppModule? If we were going to use it directly in one of the Trip components then we would provide it there.My name is Sourav Mondal.

Home ASP. Generating dynamic menus is a common task if we have big web application and user will have role-based features. If our application is simple and not any role based website then, in that case, we can create a static menu and use it in our website. Let's now consider our application is a role-based application with the different type of user, who can get different features based on their role then it will be hard to maintain with a static menu. Today I will show you how to build multi-level navigation menu with AngularJS where menu data comes from the database.
This type of menu creation is very useful when admin user wants to set the access permissions or restricting users from accessing some pages at runtime. Sourav Mondal. My Progress Track your progress. Labels Cloud ASP. Follow on Twitter Tweets by dotnetawesome. Follow on Facebook. Recent Posts.
