Modal Page

Hi everybody.

I have a "Find" button near an input box in a page, and i want a modal page, with the options for that input box, to be shown after pushing the button. After choosing an option, the modal page will be closed, and the option will appear in the input box of the original page.

The modal page will show options readed from a SAP table.

Can someone help me to know how to do this?

Thanks in advance.
