Grouping Items or Domains
Organizing a domain list can be much more comfortable by grouping a particular column. Therefore, you will good to see a list of your domains with a better view.
When the domain list on the table is grouped by a single column, data rows that have identical values in this column are arranged into groups. And each group is identified by a group row.
Using the Group Panel
By default, TLDrop hides the group panel. You can show this panel by right-clicking any of the column's header and click Show Group By Box menu.
Then you need to drag a column you want to group and drop it onto that panel. To ungroup the column, just drag it back to the main table.
Using the Context Menu
This method is even simpler, all you need to do is invoke a column's context menu by right-clicking its header, and click the Group By This Column menu.
