fix bug on removing support

- ah, the code i write is to describe the unmormal thing happen here, i didn't write the expected way as i am not sure how users make suggestions via manually typing the url. What do you think how they make suggestion via the manual url?
-when users manually type the url, the suggestion box and submit button are there, and the submit button will  be disbled. When"support this initiative" is clicked, the submit button is abled?
-or when they maually typing the url, the suggestion box and submit button will not appear. when click the "support this initiative" they will show up?
-or anther way?
