well, markup inheritance lets you create pages (or panels for that mater) with the same layout. Suppose you want to have two pages that both have (the same) header and a footer. Markup inheritance is a way of doing that (there are other options as well).
So what you do is, create a Base page. In that page you will add the header and footer normally as in any Wicket page. the html will look something like: <html> <body> <div wicket:id="header"></div> <wicket:child/> <div wicket:id="footer"></div> </body> </html> * I eliminate the java code as it is supposed to be simple. But remember, you add the header and footer wicket components in THIS page Now, in pages SubA and SubB you can add whatever you want. It will be put where the wicket:child is located. So, 1. in the html <html> <body> <wicket:extend> ... Here all the sub stuff will be put </wicket:extend> </body> </html> * actually the <html> and even the <body> tags are not really necessary, but I am used to put them so my IDE won't get crazy :) In the java you need to extend the base and add the components according to the ones you added in the html. you DON'T need to add the header and footer in the subclasses.
