single listbox in multi-input

i still wondering whether i could build a listbox that may consist a lot of data. for example, if user choose item that user want from the combo box, the name of the item, price, taxation price will be include in a listbox. so is there any way to do it ? any comments?

graphical :

title price ... <-- label box
-------------------------------------------------------------------
|abc book 5.00 |
|music book 6.00 | <--
|cafe 3.00 | a listbox
|math 8.00 |
------------------------------------------------------------------|

the space between the title and price, is it using tab() concept?

the graphic is wrong anyway, i will fix it, hope that it can work

title price ... <-- label box
----------------------------
|abc book 5.00 |
|music book 6.00 | <--
|cafe 3.00 | a listbox
|math 8.00 |
