I'd like to be able to add custom fields to blocks in Drupal? I have a header area that spans the entire width of the page. Below that will be a left column for body content and right sidebar for various blocks. The header area needs to have a background image with text displayed on top of it. Was hoping to do this through blocks with custom fields for the background image and text.
You could achieve this using the Views module, Fields and blocks.
For instance you could set up something like this using field replacements in views:
<div style="background: [field_image] left top no-repeat">
<h2>[title]</h2>
<p>[field_whatever]</p>
</div>
It seems like a bit of overkill, but it would get it in the hands of the client. You'd also want to do something restrictions to keep it only using a certain node ID so that they don't create a million background image nodes and wreck the site. Hope this helps.
