This spring it was the first time I worked as a freelancer. My main task was scripting a form with autocomplete elements. These elements were connected with each other. I decided it would be easier to work around own mechanism of autocomplete combobox component. The first thing I did was a simple html markup and several listeners. I managed comboboxes (primarily refilling and setting as disabled) manually. After I finished the job I thought about making a jQuery plugin from the stuff. Finally I ended up with this.
