thanks all. but what about the default "Please select a value" option? how can i have it such that the user either - cannot select that option - shown only on 1st run - can select the option but will cause the 2nd dropdown to empty - dunno if this is good idea
or any other suggestions ? btw, as for plugins theres also the jquery Cascade. but the thing is how can i also populate the 1st drop down dynamically? the plugin only handles for 2nd and subsequent dropdowns
