Mario, Thank you for evoque, and integrating it with Gizmo(QP). On the evoque website would it be possible to show some typical example template files? I am keen to see how to put and call multiple sub-templates in the same physical file (provided of course they all use the same overlay template). I am trying to aim for one template file per Directory class with each Directory component having its own sub-template in a $begin{xyz} .. $end{xyz} block. But have been unable to do it so far. As all the sub-template blocks use the same master_template (_template.html) I am expecting it to be ok to have all the sub-template blocks in one file, as there only needs to be one overlay statement? I could solve the problem by using one sub-template per file (like the examples that ship with Gizmo(QP)) but I kind of like having all the sub-template blocks in one html file, as opposed to multiple files or using qpy methods to fill in the sub-template specific template content. I am sure I am missing something and just need a solid example(s). Tristan
