You can show the contents of one page as a rendering within another page by two similar methods:-
If there is a page ], you can show the contents of that page within your page by simply including the code {{Xxx}} in the text/code of your entry, to invoke the Template:Xxx. See Help:Template for in-depth help on Templates.
Please note: By Templates, we mean those entries in the Template: namespace. Templates are designed to be used for a number of purposes
Please do not use the Template: namespace if the code you want inserted into other pages is not to be inserted in many pages. Please use the second method below.
This method is similar to the above, but without using the Template: namespace. This method is used in a few places in Wiktionary to maintain a list of items in one page, and then "quote" that page within another. This may be used because it is easier to maintain the list separately; to quote it in more than one place; because the list is protected and the page it is inserted to is not, or vice-versa.
Simply reference the one page within the other, using double curly brackets {{target-page}} instead of double square brackets. If there is a Template of the name Template:target-page, that would be displayed. But if there is no such Template, then the contents of the page ] will be displayed.
e.g. {{Help:Contents}} or {{:Apple}} Note: you need the colon.
