MediaWiki extension NewPageTemplateSelector is similar to InpuBox::create but allows to specify list of templates to choose

Usage:

 <NewPageTemplateSelector 
                          templates="Empty article, Article about a feature,Article about a product" 
                          placeholder="Please enter a page name"
/>

As usual, you can use articles from the MAIN namespace use as a template

The extension does not contain any JS code and uses OOUI.
