Display only parent project in multi project custom templates

Hi Folks,

I am working on multi project solution templates and packing them in VSIX.I have 3 class libraries and one web application.

When I install the VSIX,all the projects get listed in the New project.I want only the parent(parent.vstemplate,linked with 3 class libraries and 1 web application) to be displayed, not all.

How to proceed.

Regards

Soni
