make drop down list item unselectable

I have an asp.net dropdownlist and would like to make some values disabled to select. We have a list of 10-100 items that will be in the dropdown list. Users need to select an Item to perform a function.

Each item has a Heading that it’s sorted on, 10 items under 1 heading (example). and I want to not allow the heading to be selected.

Try for each element you want to diable:

  ListItem i = DropDownList1.Items.FindByValue(str);
  i.Attributes.Add("style", "color:gray;");
  i.Attributes.Add("disabled", "true");
