[FIXED] How to tell Netbeans to treat a mustache file like a html file

Issue

I am using Netbeans 12.2 and I am editing a file which its extension is .mustache.

Apparently, Netbeans doesn't recognize this file extension and there are none colors inside the editor. Is there a way, to tell Netbeans to handle this file like an html file?

Solution

You can associate a file extension with a mime type in Tools -> Options -> Miscellaneous -> Files.

To create a new extension, click on the "New" button:

Then select that extension and associate it with HTML files:
