gnome-hud | Unity like HUD menu for the GNOME Desktop Environment | Menu library

Try something like this:

You need to work with type of generics type to use .allCases.

Here is fixed variant (modified parts are highlighted inline). Tested with Xcode 13.2 / iOS 15.2

You need to move the $Computer = Read-Host ... statement out of the Invoke-Command statement:

You are so close to the solution. I really appreciate you for that.

I have deployed the code to the dummy URL: https://distracted-pasteur-66c13a.netlify.app/

You can use the following CSS to make your navbar sticky.

As suggested by kleopatra modified the code as stated below and it works well.

Your solution is the correct solution and does indeed improve the accessibility for keyboard users.

If you need some reassurance check the W3 examples for a flyout menu

Much better than tabindex="-1" would just be to add display: none via a CSS class and change the menu item to a (assuming the top level menu item is not a link). Then opening the menu is as simple as toggling the CSS class and avoids any potential errors with managing tabindex.

If the top level item is a link to another page then follow the principles of option 2 and have an additional drop-down icon next to the main link instead (with aria-label="open (menuItemName)" for example).

The final consideration is that once a menu is open that is a "mega menu" style (multiple columns), you should ideally implement arrow key navigation to take you between columns and items.

As for whether pressing Tab should go to the next top level item it is something that I am not sure if there is any guidance on, I personally say yes it should and arrow keys are for navigation within a drop-down, but I would make it a true drop-down with aria-owns on the

If you have the knowledge of how to implement WAI-ARIA correctly then that is the best option, if not then making the Esc key close the mega menu and or pressing "up" when at the top of the list to get back to the top level links is a reasonable compromise.

I do have one other thing you can do straight away (I know sometimes there is not the scope to fix things right now) as a stop-gap "solution".

Add tabindex="1" to the search box so it is the first item that receives focus and make sure you have "skip to content" links so people can bypass the menu.

While this certainly does not solve the issue, it does improve accessibility / UX for keyboard users in the short term while you fix the problem, and although it doesn't follow "logical focus order" it would be a better experience (as a temporary fix).

Something that you can do quickly while you explore a more robust solution to the mega menu with arrow key functionality etc. etc.

I will stress this point one more time, this is a temporary improvement, not a fix!

The _options variable is a class variable. It's shared among instances of Menu class.
Make it an instance variable to make it private to an instance.

You don't need to change anything, your code should work. You can check the user preferences menu item in web module (similar to your menu item).

You are using navigation architecture components, so the navController is the one that should control fragment transactions, you are doing that right with BottomNavigationView.

But within the navDrawer you are doing the transaction through the supportFragmentManager which should be done through the navController instead as both handle the navigation differently.

whenever I select an option on the menu(say settings), it displays the contents of the option along with the bottom navigation view

That is because the BottomNavView is a part of the activity, and you need to move it to a fragment; this requires to change the navigation design of your app; to do that change your app navigation like the below:

Main navigation:
