Implement Multi-select HTML combobox on 1 WEB PAGE

Your job is to implement a multi-select combo box similar to <[login to view URL]> in the following website: <[login to view URL]> Our website <[login to view URL]>? is quite ugly and unweildy to look at.? We think by 'collapsing' the functionality of a multi-select combo box, it will make it more attractive. if you can do it, let me know the total time of implementing this and the total cost, you'll certainly be first in line. If you have code somewhere on the internet that proves that you've coded such functionality before, you will certainly have a high preference for getting this job. The code must work on all browsers.? When submitting the form via post, the post submission should post the same values as <[login to view URL]>? We need this done asap. ## Deliverables This can be programmed in php, Javascript, html.? The code MUST work on all browsers.
