default text in filter textbox of cgridview

hi all!! I want to have default text in ma filter textbox of cgridview.

Eg.If i need to filter age column then,the default text should be some thing like "enter age" and on focus of that text box it should disappear.

has anyone used something like that??

Thanks

For this you need to use JS or jQuery…

do i need to convert it into a widget and then apply?
