List of values in Oracle Reports 11g parameter form

Hi everyone,

We want to implement list of values in Oracle Reports 11g parameter form with combo box and type option.

For example the user should be able to type and select the list of values from the combo box.

If we implement unrestrictive LOV then it shows all the values in the HTML page; instead of that if the values can be show in the combo box with using restrictive option.

Thanks
