Hi,

I tried googling around, but I couldn't really find what I am looking for. What are currently the options of changing the behaviour and content of standard (new/edit) pages? See below for the scenario I would like to create.

I would like to create address lookup based on postcode details. For this I would like to modify existing pages for accounts.So I created a sidebar component and added some javasript to modify the components. Unfortunately, when deploying to sandbox I found out that it will not work, because different server addresses for the visual force servers

[code]

window.parent.document.getElementById('acc17country')

[/code]

Since the account has a lot of fields I don't really like to go into the way of full recreate the new/edit pages with a new visual force page.

So I am looking for ways to modify the content, I know there are some things possible like adding a (floatable) picklist for the countries in this app CountryCompleteFree. But I cannot really understand how they are doing this. Any help will be appreciated.
