Hello
I have a question regarding highlighting of selected item in navigation view. I noted a behavior in context of subitems where I'm not sure if it behaves like designed or if it is a bug. With term "highlight" I mean the small colored block that appears at the selected item.
For demonstration I used from WPF Demos the "Sub Items" example. Attached there is a Windows steps recorder session (can be opened with e.g. Internet Explorer) that contains screenshots from every click and I can refer to the step numbers.
I can observe the behavior when navigation view is collapsed (shows only icons).
Short:
After a subitem was selected the highlight is not shown anymore when selecting the corresponing (main)item.
Long:
First I switch between different items with and without subitems. Everything is like expected, the selected item shows the highlight (Step 1 - Step 12).
Then I select a subitem. Still, highlight is shown at (main)item (Step 13- Step 14).
Next I click on another item that still behaves fine (Step 15)
Now, when I click again on the (main)item, where I selected the subitem before, the highlight is not shown anymore (Step 16)
I can click on the item several times. Just the subitems (dis)appear but no highlight (Step 17 - 19)
Only when I select a subitem the highlight appears (Step 20 - Step 21)
Again, click on (main)item, it is selected but no highlight (Step 22 - Step 24)
Is this behavior intended? If so, can someone explain me the idea behind it. For me it feels strange at the moment.
Thanks and regards
Philipp
