The Syncfusion® native Blazor components library offers 70+ UI and Data Viz web controls that are responsive and lightweight for building modern web apps.
.NET PDF framework is a high-performance and comprehensive library used to create, read, merge, split, secure, edit, view, and review PDF files in C#/VB.NET.
I'm not sure if this is an issue or if we're doing something wrong, but there seems to be an issue with the Menu when trying to change the focus with the arrow keys, with Tab it works fine.
We're using version 15.3.0.33 on a Fall Creators Update project.
On the following video you can see it a bit more detailed with two issues, one when we're on the sub-menu of an item and then another one when we're outside. It seems that when it should close the submenu it just crashes instead of going to the parent item. And the second error is when trying to navigate the parent items from left to right or right to left.
The error:
System.NullReferenceException: Object reference not set to an instance of an object.
