How to hide sub project templates in visual studio?

I created multiple project template and rename .vstemplate files. And I created VSIX extensions.

But I want to show only multiple project template. How can I hide other sub templates ?

Solution

You can keep your sub templates hidden, by setting the Hidden element in your sub template's .vstemplate to true. See the following doc topic for reference:
