There isnt one. The drop down cannot be used as a text entry field. It is automatically read-only. Think of it this way. A dropdown is nothing more than a listbox with the ability to not take up as much space on the page by offering the option of the dropdown list.
Ohhh i think i didnt explain properly. what i mean is that how to Freeze Drop down list. i have a drop down list with 5 elements. but i want to freeze it on html page so that only the first item is selected by default and user cannot change it.<BR><BR>does it make sense ??
