Please find the attachment.
The purpsoe of selecting a site is to display its specific details where we have already broken it be using set analysis, so we can make it show like below
this will tell the user that the black bars are not applicable for the selected site(3 in this example).
Or if u want the site selection not no be effecive anywhere then there is no purpose to have the list box there,
Still fi u need to have the list box there and wan to stay numb u can put it in a different alternate state this will result in below
Hope u know Alternate states. In the attached app i have created an alternate state called without selection and applied it to the list box in the above pic.
Hope this helps.
