Menu bar component

[Angelinsky7]

What is the expected behavior?

When creating a menu inside a toolbar when clicking on the first item (a button that open a menu) i would except the second menu to open when the mouse enter the next menu item in the toolbar.

What is the current behavior?

You need to click on the second item of the menu to open the second menu. This is totally logical, because root menu items are simple button, but if you try to create a complex menu toolbar, users are used to menu that open automatically without the need to click (apart from the first time)

What are the steps to reproduce?

you can look here for the kind of menu that i mean : https://stackblitz.com/edit/dynamic-nested-topnav-menu?file=app%2Fapp.component.html
if you click on the first item ('DevFestFL') and them move your mouse on "Didney" or "Orlando" you would except, as a user, that the corresponding menu open automatically. Instead, you need to click on the item.

Which versions of Angular, Material, OS, TypeScript, browsers are affected?

"@angular/animations": "~7.2.0",
"@angular/cdk": "~7.2.1",
"@angular/common": "~7.2.0",
"@angular/compiler": "~7.2.0",
"@angular/core": "~7.2.0",
"@angular/forms": "~7.2.0",
"@angular/material": "^7.2.1",
"@angular/platform-browser": "~7.2.0",
"@angular/platform-browser-dynamic": "~7.2.0",
"@angular/router": "~7.2.0",
"core-js": "^2.5.4",
"hammerjs": "^2.0.8",
"rxjs": "~6.3.3",
"tslib": "^1.9.0",
"zone.js": "~0.8.26"

Is there anything else we should know?

I understand why this is happening and it seems that we would need to have something like a mat-menu-toolbar that could automatically 'open' a mat-menu-item and show it to the user (horizontally or vertically) like that we could have a coherent way of showing simple menu and complex one without so much effort.

thanks !

This sounds similar to the menu bar component we had in Angular.js Material.

Thank you for submitting your feature request! Looks like during the polling process it didn't collect a sufficient number of votes to move to the next stage.

We want to keep Angular rich and ergonomic and at the same time be mindful about its scope and learning journey. If you think your request could live outside Angular's scope, we'd encourage you to collaborate with the community on publishing it as an open source package.
