TreeGrid / Expanding Column


This sample shows how to change the column which contains the expand box for rows, in TreeGrid directive for AngularJS. By default expanding column is set to be the first column. By selecting a different column from right panel, you can change that so expand boxes can appear in some other column.

The following method is used:

  • expandColIndex(name, index) - sets the index of column which will act as expanding column
