Configure the Toolbar and Menus

The Gantt toolbar contains the following button groups, each conditionally visible based on your configuration:

Button	Visibility Condition	Description
Edit / Close Editing	Hidden when `readonly=true` or `alwaysedit=true`	Enters or exits edit mode
💾 Save	Visible in edit mode only	Persists pending edits to Polarion
Undo / Redo	Visible in edit mode only	Reverses up to `undo_steps` changes (default: 10)
➕ New	Visible when at least one type has `enableCreate=true`	Dropdown to create new work items or plans of an enabled type
Collapse All / Expand All	Always visible	Collapses or expands all parent rows in the grid
🔍 Zoom In / Zoom Out	Always visible	Steps the timeline scale in or out
Go to Today	Always visible	Scrolls the timeline to today’s date
Filter by Item	Visible when items are selected	Filters the chart to the selected work items and their related items (parents, children, and dependencies)
Search	Always visible	Text filter by work item ID or title
Fit to Page	Always visible	Fits the Gantt to the available working area
Compare with History	Always visible	Compares the current schedule against a previous (historical) version of the items
Toggle Automated Scheduling	Visible in edit mode	Turns auto-scheduling on/off, so moving a predecessor reschedules its successors (see Configure Auto-Scheduling)
Toggle Critical Path Visualization	Visible in edit mode	Highlights the critical path (the longest dependency chain)
Toggle Dragging Children with Parent	Visible in edit mode	Whether moving a parent also moves its children (mirrors the hamburger-menu option)
Toggle Hide No-Task Resources	Visible when the resource view is shown	Hides resource rows that have no allocated tasks
Refresh	Always visible	Reloads Gantt data from the server (also in the hamburger menu)
Print / Export	Always visible	Opens the export panel for PNG or print
Mark Differences	Visible with derived schedule types	Highlights items with unsynchronized dates
Clear Calendar Cache	Visible when `useCalendarCache=true`	Clears server-side calendar cache and reloads
⚙️ Parameters	Visible in maximized view only	Opens the Page Parameters panel

The exact set of visible toolbar buttons depends on the widget configuration, the installed version, and whether the resource view is enabled. Button labels above match the in-product tooltips. Hover any toolbar icon to confirm its action in your installation.

Set the widget parameter hide_toolbar to true to hide the complete toolbar. You can also set this as a default via the configuration property:

nextedy.gantt.workitems.default.hide_toolbar=true

The widget parameter value overrides the global configuration property. Set hide_toolbar=false on a specific widget to show the toolbar even when the global default hides it.

Configure Edit Mode Behavior

Control how editing works using two widget parameters:

readonly: Set to true to disable all editing. The Edit button is hidden, and drag, resize, and add-task operations are blocked.
alwaysedit: Set to true to keep the Gantt permanently in edit mode. The Edit/Close buttons are removed, and tasks are immediately draggable.

If both readonly and alwaysedit are set to true, the Gantt operates in read-only mode. The readonly flag takes precedence.

Configure the New Button

The ➕ New dropdown lists all work item types that have enableCreate set to true in the Work Item Types Configuration. Each type appears with its icon and name. To hide the New button entirely, ensure no work item type has enableCreate=true, or set the EnableCreateNew flag to false. Click the ☰ hamburger icon in the first grid column header to access quick actions:

Refresh — Reloads Gantt data from the server
Drag children with parent — Toggles whether child tasks move with their parent
Go to today — Scrolls the timeline to today’s date
Set scale — Submenu to change the zoom level (Day, Week, Month, Quarter, Year; Hour appears only when the widget is in High Precision (Hours) mode)
Column visibility — Submenu with checkboxes to show or hide individual grid columns
Help — Opens the Gantt documentation site

Use Context Menus

Right-click on different areas of the Gantt chart for context-specific menus:

Column header — Right-click to show/hide columns via checkboxes
Timeline header — Right-click to change the zoom scale or navigate to today

Hold Shift while right-clicking to bypass the Gantt context menu and access the browser’s default context menu.

Configure the Parameters Button

The ⚙️ Parameters button appears in the toolbar only when the Gantt is in maximized (fullscreen) view. It opens a scrollable modal dialog where you can modify all widget parameters without editing the wiki page source. To force non-maximized mode via URL, append ?MaximizeGanttView=false.

Verification

You should now see only the toolbar buttons relevant to your configuration. If you set hide_toolbar=true, the toolbar area should be completely hidden. If you configured alwaysedit=true, task bars should be immediately draggable without clicking Edit.
