Missing topics

This page is for listing topics missing from the current Theming Guide, pursuant to the effort to analyze and tag the Theming Guide for a better information architecture. This page is freely editable by anyone with a Drupal.org account. If you have reviewed the Theming Guide but could not find a topic you were expecting to be here, please add it below. We will also all need to regularly review this list to determine if the content is really missing, or just wasn't found. If something listed here does exist, please add a link next to the item. Topics that should not be included in a theming guide will be removed.

- I didn't find anything about the fact that code must be appart of the presentation.
- In the drupal module tutorial, they say that we don't have to inject <br> into the php code and that we must create variables that contains data and a template that contains layout. But how can this be done ?
- What variables do I have to create ? How can I link a template for a module ? How do I call a variable in the module template ?

- In-depth page needed for themeing highly stylized/structured CCK data sheets. Not CCK forms as shown on this page http://drupal.org/node/101092 and elsehwere. But rather where you have data and are seeking to output it into tables or specific div layout or whatever. I've just spent 2 days figuring this out. Could have done in 4 hours if I'd had a proper how-to page to guide me. The basics are shown here: http://drupal.org/node/532920#comment-2097592.

D4d designers are working on similar goals, we're making an inventory of things frontenders run into / need to learn when starting out with Drupal.
- initial list: http://project.designfordrupal.org/org/node/68
- first proposal for how to group these topics: http://project.designfordrupal.org/org/node/62
Will try to keep this updated here.
