cWebMenuColumnList is a menu item that can show a list of all columns in the web list with a checkbox next to them, indicating to show or hide the column. A column item can be clicked and will result in a toggle of the current state.

The cWebMenuColumnList is shown in the web list's header menu if pbAllowColumnHiding is set to True.

A cWebMenuColumnList can be extended with extra child menu items, but these will only be appended, as the Choose columns and Restore layout will always be at the top.

You must set pbUseCustomHeaderMenu to True in the cWebList/cWebGrid to use a custom menu.

Note that the control can only be used in a cWebContextMenu and only with either the parent or phoControl set to a cWebList-compatible control.
