And I would like when user select, for instance, text "AAA - week - 4" or "DDD - week - 4" another drop down box will invisible. The same situation when user will select values 2 or 3 or 6 the textbox becomes invisible. But actual drop down list has almost one hundred similar values.
You cannot do this with a drop down as you cannot multi select from a drop down list. You can achieve this with a list box if you check the "Allow Multiple Selection" Check. You have to use something like"
if (ListBox1.rawValue == "1" + "\n" + "2") //I used the "\n" because the selection will add a return. This way I am searching
