InfoPath Dev

-hey I am in a process of designing an web form which has 20 columns and 150 rows. 

-The user selects one of the value from the drop down list and accordingly the correspondent  type ofweb form has to be loaded.

- So the basic idea is to have one form with three different views.

So these are my questions...

- I need to know whether I can be able to  hide the rows ( If i use tables) and also its data according to the type of form user selects.

- The form has some static fields filled in already and also dynamic fields which require the users i/p. The data they fill has to be saved in a list. What is the ebst way to do this with minimal coding.

- and also Each form is attached to a particular id. So, The user should be able to open the same form with filled in data when he selects that id. So can I both submit the data and also save the whole form..?

Thanks

I don't understand all of what you're saying, but I'll try to answer:

1. You can have a main view with the initial pulldown, then upon selecting something in that pulldown, you can switch the view on the fly
2. Each view can have different controls that are bound to different data elements and that show different information
3. You can show whatever you want to show or not show by using conditional formatting
4. does i/p mean input?  If so, I'd suggest just typing out "input," since i/p can stand for many things, namely InfoPath.
5. When submitting the form, the data gets posted to the form library as long as you promote those properties during the publishing of the form
6. When submitting the form, a new XML data form is created that gets put in the library AND all the data that you promoted is placed into the library view - you  have control over all of this.  After initial submission, users can re-open the same form and view or modify the data if you choose to let them.
