how to edit item list box in webdynpro abap

Hi Experts,

How can we make item list box to editable,means we are giving option to user to enter their values based on requirement..like 1 to 6 or 1 to 10.

the main agenda is to give option to user to enter his values and save...I am trying editable alv ..but lookwise there is a problem with height and width.

kindly suggest me is there any other UI Elements.
