Write some Software

I have already created a website using the PHPMaker V12. Here in the generated code I would like to put some of Custom Forms/code. 1) [login to view URL] ([login to view URL]) In the Account Text Field & Party Name Text Field, as soon as we start typing a list box should be open on the right side with the possibility list and we have to select from it. (the value should be ID and the display should be NAME) 2) [login to view URL] ([login to view URL]) In the Party Name, Sales Ledger & Item name, as soon as we start typing a list box should be open on the right side with the possibility list and we have to select from it. (the value should be ID and the display should be NAME) 3) PHP code to get Value from the POP UP Dialog Box. Note : The above link is not the final design. This is just to explain what I want. The freelancer should design for the best look with the proper coding. Here we can not change the header and footer as it is a generated code. So I have attached with the generated code and the css file use in the project.
