I'm using Intellij Idea 2020.3 Ultimate Edition on macOS.
When I create a html file named 'createItemForm.html', Intellij doesn't recognize it is a html file.
When I create another 'createItemForm.html' file in another path, it isn't recognized too.
The source code of 'createItemForm.html' is shown below.
All html files except that name are recognized.
Could you tell me what's wrong with my Intellij?
