Add a Custom ColumnMenu Checkboxes Filter to the TreeList

Environment

Description

How can I create a custom column menu filter with checkboxes for a column in the TreeList?

Solution

A custom column menu should be created through the filterContent property to the custom filter we want to create. In the custom filter we can render a list with checkboxes, whose onChange event calls the onColumnMenuFilterChange event, which sets the state of the filter and updates the TreeList accordingly.
