It really depends on what information is in the F4 lookup window. Is the data static? If so, that should be pretty simple to handle while developing the transformation. If the data is dynamic then it depends on whether you have some way of accessing that information to retrieve it prior to displaying your page. If you don't then there is not much that can be done. You would need to find some way to extract the data to have available to populate the drop down list. Without knowing your options there is not much we can suggest.

You could have two transformations for the screen depending on a global variable.
If the global variable contains the values you need. Then use that.
If it doesn't, have the transformation prompt the right field and collect the data on the resulting screen. Either with a business function, or simply by having it press the right key and having another transformation recognize the next screen, collect the data, and exit.
Then, the variable will be populated. Use the global variable to populate the drop down.
Remember to clear the global variable whenever the value is not valid any more. If it is on program exit, or maybe per session?
The easiest way would of course be if you could have the background application put out the values on the screen with non display. You will be able to collect them, and they will still not show. Saves a bit of time. It will depend on how much space you have on screen thought.

Well. As I said. You may collect the values automatically. If the list is on several screens it is a bit more complicated but not much. If the position on the screen for the window varies, I would go for a business function rather than a transformation. I would not recommend having more than maybe ten values on a drop down thought. It just gets messy.
Regarding the more option. I wouldn't.
Think of it like this: If you have HATS scroll the list to the bottom each time you are taking much more time than the user would by scrolling just as much as he needs. Why bother?
Also; In order to be consistent you would need to do this on every subfile. And that is just not practical. Some of them are surely very long! A drop down of moderate length thought is, at least in my systems, a common component and would not promise the users something they cannot always get.
The users are accustomed to the more button.
If you really insist, and just writing what occurs to me right now, you could probably cheat and make a false scroll bar by adding some more data than what fits on the screen and trigger the page down/page up on scroll events. Problem is; You never know if you are on the first page. You could guess by counting page ups and down. But it will depend on how consistently your background application behaves on page up. It will also be rather obvious as it will still jump a page at the time. You could probably do some AJAX stuff to load to load more data when the user scrolls past the available shown data. That would solve the page up problem. And give a smother scroll. If you do a nice animation while it is loading data it would be ok scrolling down too, I think. I really wouldn't do any of this. If you do, please post your code. I'd like to see it!

Thanks Gerardo for reply
As you specified i tried by writing a macro and capturing all the more options in a dropdown list .But i can't be able to diplay everthing in a single scroll bar, if you /some body have done this functionality before can u please share me the code snippet . so that i can be able to check as a reference .

You just have the macro scroll down and repeat itself if there is a more on screen. The captured data you then use in a drop dawn component with the "fill from global variable"-option.
If the list is long, this will be slow and the drop down hard to use for the users. Only do this with short lists. If you have to collect several pages, you should consider if it is really worth it!
And you can really only use this data in ANOTER screen! You can not expect to interact with the collected data.
Also best to condition the data collection on the existence of the variable. So you do not collect identical data if it is already there.
I have no code to share. I do something similar in one case. The data is collected at startup and normally contains three or four values. Although I do have a provision for paging down for super users. Unfortunately I use my own components and it really is not much to it, just a transformation and a businessfunction that either finishes with a page down or a F3 depending on if it is done or not. It even to simple for a macro!
