Display No. of column based on multiselect parameter

[rajeshbcrec]

HI,
i want to display the that many number of columns as many i will select in multiselect paramter.In my example four parameter is there and four fields are displaying.
so when i select "First Column" in parameter then only first column should be displayed .
when i select "First Column" and "Second Column" both at a time by pressing ctrl ..then it has to display both the columns and so on.

please suggest any solution for this.

Thanks
