Hi - I am quite new to Drupal and having an issue when it comes to creating my own custom dropdown menu. For some reason it always breaks the layout of the main content below it... I have been trying multiple ways of getting rid of it - trying different css dropdown code, trying to reverse the move by making the margin -600px... etc...

Any help would be much appreciated as this had got me stumped.

Please have a look and let me know.

First of all, I'm a beginner in Drupal thus this question refers to some basic aspects of theming.

To better visualize my "problem":
1) I'm adding a new, custom block to the page via Administration => Structure => Blocks
2) In the field "Block body" I'm adding some text (plain text)
3) I'm assigning this new block to a particular region in my theme

Now I go to my website to see the new block content. I use Mozilla's Firebug plug-in and see that the text from the "Block body" is presented within these tags:

I know you shouldn't edit the core themes as this can cause problems in the future, but is it ok to install a new theme into /sites/all/themes and edit these? Will editing these themes cause problems in the future like editing core themes can?

Cheers

Hi all,

I am currently developing a site where on the landing page a user can kick a button where it will apply 1 of 2 themes until that button is clicked again. The theme must stay even if different pages are loaded.

I have been experimenting with the ThemeKey module (http://drupal.org/project/themekey) which is pretty amazing, but I cannot seem to define a set of rules which will allow this.

Hi, I searched but could not find...

Is there a comprehensive list available of which browsers Zen 7.x.5.x should work with out of the box? I simply cannot install every version of every browser to test with.
