Dear support, very compliment. Dijit is fantastic, i tried use this in my application. I apologize for my not so good english. I have 3 very simple question about the "ComboBox" element.

1) I want unable the user, insert text free. I want, he can only a item from the drop down list select. Is possible, an yellow alert, same as in the "data box" when the user insert a incorrect format date?

2) I want, an opening page, a courtesy message "please select a option!" in combobox see, and when the user put the cursor in combobox, i want this message delete and the combobox clean. Is possible?

3) In my combobox i see a square arrow, in dojo site example an circle arrow. How can i this circle arrow download and change?

Very, very thanks!
