How to Output PHP Code through CMSB?

This has really got me thinking :)

We need to select a page template for the layout of page, and a CSS templates for the "theme" of the page.

I guess firstly, there has to be some base template... ie. headers | navigation | content | footer. And then the templates could aply to the "content" area, ie. 1 column, 2 column and 3 columns.

Then, within CMSB, have a "modules" section... for dynamic content, ie. News Module, Gallery Modules, Advertising Module, Product Module etc.

Then, define for each module, 2 php includes, one a simple style that would fit in a side column, and the other a detailed style that would fit in a main content area. I think each include should utilise similar CSS. This way, we could globally define themes quite easily.

I would build the navigation of the site, with the top level set with standard buttons, and the drop downs grown from a multi-section editor in CMSB. As you add a record, you choose a "category" so to apply it to the drop-down for that button.

In that editor, have a title to appear in the drop down, then choose which page template (1, 2 or 3 columns). Using the Show/Hide Dependant Fields plugin, this will give you 1, 2 or 3 content areas. Also, which theme template (or this could be site wide).

Within each content area have the ability to select which "module" you want to appear. In the 1st or 3rd columns, the choice of "news" would then add the simple news inlcude into the page, whereas choosing "news" in the 2nd column would include the detailed include.

Each column should also have a WYSIWYG field, so if that column only had text - so be it, just select "none" for the module choice. Or, you could use the field to include an introduction before the modular content.

So, in theory, this should deliver;
1. A consistent style to the site
2. Ability to choose page layouts for individual pages
3. Ability to choose modular components to any section of the pages
4. Ability to select css themes to the site / page.

This will all work for list pages, but would need to think about the detail page for a module...

There's my brain dump :) your thoughts?
