Toggle Columns via the Context Menu
Right-click on any column header in the Gantt grid to open the column visibility context menu. The menu lists all configured columns with checkboxes indicating their current visibility state. Click a column name to toggle it between visible and hidden. The change takes effect immediately — the column appears or disappears from the grid without a page reload.First column cannot be hiddenThe first column (the task title column) is always visible. Its entry in the context menu is disabled and cannot be unchecked. This ensures you always have a reference column identifying each work item in the grid.
