Frozen Rows and Columns in Vue TreeGrid component

08 Dec 2021 / 3 minutes to read

Frozen rows and columns

Frozen rows and columns provides an option to make rows and columns always visible in the top and left side of the tree grid while scrolling.

To use frozen rows and columns support, inject the Freeze module in the provide section.

In this demo, the frozenColumns is set as ‘2’ and the frozenRows is set as ‘3’. Hence, the left two columns and top three rows are frozen.

Freeze direction

You can freeze the tree grid columns on the left or right side by using the column.freeze property and the remaining columns will be movable. The tree grid will automatically move the columns to the left or right position based on the column.freeze value.

Types of the column.freeze directions:

  • Left: Allows you to freeze the columns at the left.
  • Right: Allows you to freeze the columns at the right.

In this demo, the Task Name column is frozen at the left and the Priority column is frozen at the right side of the content table.
