Templates are no different from regular pages in terms of the type of content you can put on them. The difference is that templates are made with the intent of transcluding them (i.e. showing all/most of their content) on other pages. As such, they tend to contain different things from regular pages but this is a result of their purpose, not any sort of restriction.

The one exception is when you are building a basic portable infobox. When building this type of template, you can use Special:InfoboxBuilder. This special graphical editing tool will automatically place the page in the template namespace. That said, this is merely a restriction on the tools you can use, not the content itself.

If you need help adding a particular type of content to a template, please let us know what you are trying to add.
