Notification, Window or Tooltip?

[Bruno]

Hi all,

I need the following functionality:

I have an aspx simple table with names of departments from a database. The items who have sub-departments have a small icon in the end of their name in the list indicating that there are sub-departments for that department.

When I click that icon, I want to have a list of those sub-departments (from the department) that appears dynamically on the right of the icon, and I want users to be able to choose one of those sub-departments. 

Should I use a Notification control, a Window control or a Tooltip control (or other)?

Thanks,
Bruno

Hello,

One suggestion is you can use ToolTip. Here is the sample demo of ToolTip.
Grid / Insert with Tooltip
