Locked columns

Locked (frozen or sticky) columns are the columns that are visible at all times while the user scrolls the TreeList horizontally.

In order for the locked columns to work properly, configure the following options:

  • (Required) Set width of each column.
  • (Required) Set overflow: auto and width in pixels through style of the TreeList.
  • (Required) Set locked property of the column.

By default, the columns of the TreeList are not locked.
