creationg Infopath forms using Infopath Designer

you can start by creating a Form and Deploying to our SharePoint site. Our aim is to have a simple form to capture the following fields:

• Title
• Full Name
• Address

Double Click on the SharePoint List button from the first screen of InfoPath Designer. You will get the following screen. Enter your site name there and click the Next button.

In the succeeding form enter your user credentials if prompted. The next wizard screen will be prompting to enter the List Name for the Form.
Note: The form which we are creating will be used to capture item information. This information is stored as a SharePoint list.

Click the Next button and then click Finish.
You will see the following Designer screen.

The Title and Attachments are two rows by default. As you will be knowing Title is the default field required and you change the caption.

Field Pane

There is a Fields pane on the right hand side from which you can drag and drop fields. You can even add new fields using the Add Field button.
