Bulk Deletion
Form Grid now accepts the action to bulk delete rows of data (temporary deletion). Denoted by a simple check box, users can select the records they want, or select the check box on the header to select al the rows.
Select/Deselect row(s) using the checkbox, and click on the trash icon above the table to delete row(s) of table.
