Note: I\'ve read similar threads, but none quite my issue - I can right click on it fine, it just then disappears.
I find \"Inspect Element\" an invaluable tool in C
What worked for me is selecting the specific a tag I wanted to inspect and do this:

After doing the above, I would again normally select that a tag then the dropdown will automatically stay as-is even when I mouseover to other places like Inspect Element, etc.
You can just refresh the browser when doing inspecting the menu dropdown elements to go back to normal state.
Hope this helps. :)
