Like shown it in the demo in Gantt home page. I have added zoom in/out and Zoom rest buttons.
But when I try to enable the Zooming extension am getting following error
Property ‘$root’ does not exist on type ‘GanttStatic’.
Am using Angular 9 and Gantt 7.1.5 versions.
Can some one please help me to resolve this issue.

Hello Kiran,$root name to the list in our internal bug tracker. The dev team will fix it in the future, but I cannot give you any ETA.
As a workaround, you can manually add the following rule to the dhtmlxgantt.d.ts file:
$root: any;
Here is the updated file:https://files.dhtmlx.com/30d/87bf4ad23d7b4d19c7fa17336e9ab25c/dhtmlxgantt.d.ts
Or you can allow all types for the Gantt object.

Hello Kiran,https://docs.dhtmlx.com/gantt/whatsnew.html#x6629x80x6630x:~:text=Updated%20TypeScript%20type%20definitions https://docs.dhtmlx.com/gantt/whatsnew.html#x6629x80x6630x:~:text=Type%20definitions%20are%20updated
Now there are types for the tasks, links, grid columns, scales, extensions, and almost everything in the others category:https://docs.dhtmlx.com/gantt/desktop__task_properties.html https://docs.dhtmlx.com/gantt/desktop__link_properties.html https://docs.dhtmlx.com/gantt/api__gantt_columns_config.html https://docs.dhtmlx.com/gantt/api__gantt_scales_config.html https://docs.dhtmlx.com/gantt/api__gantt_ext_other.html https://docs.dhtmlx.com/gantt/api__refs__gantt_others.html
You can update to the latest version to get more features and improvements, including the better Typescript Support.
However, even if you are using the older version and don’t have plans to upgrade, you can still use the updated version of the dhtmlxgantt.d.ts file as the Gantt API is mostly the same:
// Type definitions for dhtmlxGantt 8.0.4
// Project: https://dhtmlx.com/docs/products/dhtmlxGantt
type GanttCallback = (...args: any[]) => any;
export type GanttEventName = "onAfterAutoSchedule" | "onAfterBatchUpdate" | "onAfterBranchLoading" | "onAfterLightbox" | "onAfterLinkAdd" | "onAfterLinkDelete" | "onAfterLinkUpdate" | "onAfterQuickInfo" | "onAfterRedo" | "onAfterRowResize" | "onAfterSort" | "onAfterTaskAdd" | "onAfterTaskAutoSchedule" | "onAfterTaskDelete" | "onAfterTaskDrag" | "onAfterTaskMove" | "onAfterTaskUpdate" | "onAfterUndo" | "onAjaxError" | "onAutoScheduleCircularLink" | "onBeforeAutoSchedule" | "onBeforeBatchUpdate" | "onBeforeBranchLoading" | "onBeforeCollapse" | "onBeforeDataRender" | "onBeforeExpand" | "onBeforeGanttReady" | "onBeforeGanttRender" | "onBeforeLightbox" | "onBeforeLinkAdd" | "onBeforeLinkDelete" | "onBeforeLinkDisplay" | "onBeforeLinkUpdate" | "onBeforeMultiSelect" | "onBeforeParse" | "onBeforeRedo" | "onBeforeRedoStack" | "onBeforeRollupTaskDisplay" | "onBeforeRowDragEnd" | "onBeforeRowDragMove" | "onBeforeRowResize" | "onBeforeRowResizeEnd" | "onBeforeSplitTaskDisplay" | "onBeforeTaskAdd" | "onBeforeTaskAutoSchedule" | "onBeforeTaskChanged" | "onBeforeTaskDelete" | "onBeforeTaskDisplay" | "onBeforeTaskDrag" | "onBeforeTaskMove" | "onBeforeTaskMultiSelect" | "onBeforeTaskSelected" | "onBeforeTaskUpdate" | "onBeforeUndo" | "onBeforeUndoStack" | "onCircularLinkError" | "onClear" | "onCollapse" | "onColumnResize" | "onColumnResizeEnd" | "onColumnResizeStart" | "onContextMenu" | "onDataProcessorReady" | "onDataRender" | "onDestroy" | "onEmptyClick" | "onError" | "onExpand" | "onGanttLayoutReady" | "onGanttReady" | "onGanttRender" | "onGanttScroll" | "onGridHeaderClick" | "onGridResize" | "onGridResizeEnd" | "onGridResizeStart" | "onLightbox" | "onLightboxButton" | "onLightboxCancel" | "onLightboxChange" | "onLightboxDelete" | "onLightboxSave" | "onLinkClick" | "onLinkCreated" | "onLinkDblClick" | "onLinkIdChange" | "onLinkValidation" | "onLoadEnd" | "onLoadStart" | "onMouseMove" | "onMultiSelect" | "onOptionsLoad" | "onParse" | "onQuickInfo" | "onRowDragEnd" | "onRowDragStart" | "onRowResize" | "onScaleAdjusted" | "onScaleClick" | "onTaskClick" | "onTaskClosed" | "onTaskCreated" | "onTaskDblClick" | "onTaskDrag" | "onTaskIdChange" | "onTaskLoading" | "onTaskMultiSelect" | "onTaskOpened" | "onTaskRowClick" | "onTaskSelected" | "onTaskUnselected" | "onTemplatesReady";
export interface GanttTemplates {
/**
* specifies the content of start date or end date columns in grid
* @param date the date which needs formatting
* @param task the task object
* @param column the name of the column that called the template
*/
date_grid(date: Date, task: Task, column: string): string;

There are still ways to improve, so in the future versions, the dev team will add more types for Gantt.
