Drupal 7.x

dear all,
i am new to Drupal, and now i am desperately confuse about using menu and sub-menus. i am using Drupal 7.
any body can help? if there is any tutorials shows how to make it? as an example i want to create like on this site: http://www.inter.it/aas/hp?L=en , the primary menus is a static text (not a link) then the sub-menus are shown at other part on the site. when one of the sub-menus is clicked, a specified page displayed BUT the secondary menu is still expanded,.

How can I find node number 3?
When I click at a banner which is directed to this path: http://localhost/sitename/node/3 but it shows: The requested page could not be found. Where can I find that node in order to insert the content?. If this is a deleted node, how to replace it?

I'm using a banner made with script.

While viewing webform results in admin, is it possible to add an extra field in the result-listing table?
For example I want to show the field 'city' in the result-listing table (webform-results) like IP Address and User. Is it possible to do that?

I've got a custom field setup that is a list. For example, when you create a blog page, you can select from A, B, C, or D. When a user registers, they also select A, B, C, or D. What I want is blog posts that are related to the user (blog posts that have the same custom field value the user) to be displayed on a page defined by a custom view. I've tried using a combination of relationships and filters, but I can't seem to get anything to work. Any suggestions?

Hi,

Sorry I'm new to Drupal. I am trying to add content such as "Terms and Conditions" to the User Registration Page. How do I go about doing this. I can't seem to find documentation on how to do this in drupal7

If you can point me towards a module or any tutorials that will help me that would be great thanks.

I was looking for the autocomplete CCK widget in Drupal 7, but I've seen that it's available for taxonomy only.
Is there a way to have it again?
I don't want a vocabulary for my field.
