Usually, the ECB menu (y’know that menu that says Edit Item/View Item/Manage Permissions on each list item in any view), is available only onthe title column! But in SP2010, you have the option of showing that menu on any column in the list.

Here is how -

1. From the browser, in the ribbon, choose to Modify View with SharePoint Designer.
2. Click on the field you wish to see the ECB menu in, you will see a little floatie button with this on it ">"
3. Click on that “>” floatie, and it shows a little popup dialog that looks like this -

"Common xsl:value-of Tasks"
- Show List Item Menu
- Show Link To Item

• Check the "Show List Item Menu" checkbox, save, and bingo - you have the ECB Menu on the new column.
