In this article we can explore the creation of Site Columns inside SharePoint user interface.
What are Site Columns?
Site Columns provides a central, reusable column definition. A site column can be used across sub sites or lists inside the site collection.
Creating a Lookup Site Column
In this example we are creating a new Site Column of type Lookup. The site column is needed to capture the supported state for courier services.
Currently the following countries are supported:
· New Jersey
· New York
As time goes by more and more states are supported by the courier company. The site column provides the advantage of making the change in only one place and all the associated lists are reflected with the change.
Step 1: Create a site column
Open the SharePoint site and select Site Actions > Site Settings > Site Columns. In the appearing page use the Create button to create a new site column.
Step 2: Enter the Column Details
Enter the column details as shown below:
Click the OK button to save the changes.
Step 3: Create a new sub site
Create a new sub site using Site Actions > New Site. After creating the site, create a new List inside it deriving from Custom List.
After creating the list go to the List Settings screen and select the Add from existing columns option in the Columns section.
Step 4: Add the new site column
In the appearing dialog select the Service State which should be listed.
Click the Add button to add the column into list. Click the OK button to save the changes. Going back to the list you can try adding a new item.
The Site Column is ready with the values in the add dialog as shown below:
Step 5: Testing the new site column
This concludes our creation of Site Column and using it across another sub site list.
Step 6: Adding new value
Imagine that there are around a dozen of lists using the above site column. Now the courier service added support to the state Colorado. In this case do not need to change all the lists. Instead modify only the Site Column.
Go to Main Site > Site Actions > Site Settings > Site Columns and select our Site Column for editing. Add the new value Colorado and save the changes.
Back to the list try adding a new item and you should be able to see the new value there.
