Country Wise Search

Please visit site: [login to view URL] I need to incorporate Country Wise Search In the same site. The existing script files can be transferred when the project is awarded. Please view functionality of the search, as the current thing is not to be disturbed, below are the details of the working conditions of the search : A. In case nothing is selected, the resulted will display all the featured listing only. B. In case company name is typed, there is a drop down of suggestions (unique field only) and the result gives all the company contained in the database have the word types in the text box. C. Same thing happens when words are entered in the "keyword" text box. D. In case a city is selected then the search is restricted to that city. All the above 4 point are presently work, so nothing to be done there. What I need ? 1. To add a drop down list for COUNTRY, which when selected the city fields show automatically change to match the criteria of the cities falling under the said country. 2. By default when the cities are loaded, the field show contain the text "city" and the upon clicking the list, all the cities should appear. In case a visitor presses the GO button after selecting the county and not selecting anything else or any other fields, the default featured companies in that country should be displayed and if there is no featured company then the default message as already existing in the script should be displayed. 3. When the user selects the country as well as the city and nothing else, the all the companies in that city should be displayed as per the display criteria already existing. (i.e. featured first & non-featured later). 4. In case of a key word or a company name selection then point no. B, C & D as above 5. Country to be included in the title of the detailed listing, as per the existing code. Urgent work, to be complete in 1 day.
