or for explain better if I have a list 100,110,120,130 would that each value can be used only once
OK, how are your PHP skills? This is going to require you to create a script that alters the options available in your dropdown. There is an action that is called for each form element where you can change the options available.
Take a look at this post for some information on how something like that is done.
thanks for the reply but I’m thinking of a simpler thing it would take with a eveidenziare * Entries already used type
list
100
101
102
103
then I will have when I select 100
100 *
101
102
103
etc. etc.
That is not much different, you will still need to create the code that tells the dropdown which selection to put the * next to.
