Expand form using JQuery

I have form (Ranges) that sends a Json array to MySQL db. This form contains several sections: Range, Condition and Reference. I use Ajax Select2 and MySQL to populate the drop down lists in the form. Most fields in Condition section are hidden (display:none) and will be shown based on selection of drop down list using Ajax. What I need, write a JQuery script that creates a new row with form fields for Conditions. Every Range can have multiple Conditions by a button click Write a JQuery script that creates a new row with form fields for References. Every Condition can have multiple References by a button click. Also, the new created rows needs also the option be removed if necessary. If new condition section is created by button click, a tab or button needs to be placed above the condition section to call and see the previous conditions, and see the corresponding references. You can see an example in the jpeg file. I have no access to my webserver so I send you necessary files. Budget is max €60
