-# Split task in Blazor Gantt Chart component
+# Splitting and merging tasks in Angular Gantt component
 
-In [Blazor Gantt Chart](https://www.syncfusion.com/blazor-components/blazor-gantt-chart), the split task feature enables you to divide a task or pause work when necessary, whether it's planned or unexpected. This feature adds dynamism and interactivity to the view, enhancing the visualization of project tasks on the timeline. The divided parts of a task's bar in the Gantt Chart are referred to as **segments**. You have the flexibility to both split and merge multiple segments within a taskbar.
+Splitting and merging tasks in the Blazor Gantt Chart component enhances project management by allowing tasks to be divided into segments or recombined, representing breaks or continuous work periods. This feature enables dividing a task or pausing work when necessary, whether planned or unexpected, and adds dynamism to the timeline view for better visualization.
 
-![Split task](images/blazor-gantt-chart-split-task.png)
+The divided parts of a taskbar are referred to as **segments**. Tasks can be split at load time using [GanttSegmentFields](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Gantt.GanttSegmentFields-2.html), ensuring segments fit within the task's start and end dates. Dynamic splitting is supported via the dialog's Segments tab or the context menu's Split Task option, which requires valid [GanttTaskFields](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Gantt.GanttTaskFields.html) mappings.
+
+Merging can be done using the context menu's Merge Task option or by dragging segments together in the UI. To enable these actions, set the [EnableContextMenu](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Gantt.SfGantt-1.html#Syncfusion_Blazor_Gantt_SfGantt_1_EnableContextMenu) property to **true**. Tasks must have sufficient width relative to the timeline unit and must not be parent or milestone tasks. Avoid using split tasks with multi-taskbar features to maintain compatibility.
 
 ## Binding segments data source
 
-In the Blazor Gantt chart, the [GanttSegmentFields](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Gantt.GanttSegmentFields-2.html) component plays a vital role in managing segmented tasks. The [DataSource](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Gantt.GanttSegmentFields-2.html#Syncfusion_Blazor_Gantt_GanttSegmentFields_2_DataSource) property of `GanttSegmentFields` determines the segment data source collection. It is essential that this collection be structured in such a way that the [ForeignKey](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Gantt.GanttSegmentFields-2.html#Syncfusion_Blazor_Gantt_GanttSegmentFields_2_ForeignKey) property of `GanttSegmentFields` and the [ID](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Gantt.GanttTaskFields.html#Syncfusion_Blazor_Gantt_GanttTaskFields_Id) property value of [GanttTaskFields](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Gantt.GanttTaskFields.html) act as a foreign key relationship between the task collection [DataSource](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Gantt.SfGantt-1.html#Syncfusion_Blazor_Gantt_SfGantt_1_DataSource) and the segment collection `DataSource`. Additionally, the start date, end date, and duration field mappings of the segment collection can be defined in `GanttSegmentFields`.

 ## Split and merge tasks dynamically
 
-In the Gantt Chart, you can enable dynamic splitting or merging of segments by setting the [AllowTaskbarEditing](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Gantt.GanttEditSettings.html#Syncfusion_Blazor_Gantt_GanttEditSettings_AllowTaskbarEditing) and [AllowEditing](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Gantt.GanttEditSettings.html#Syncfusion_Blazor_Gantt_GanttEditSettings_AllowEditing) properties to true in the [GanttEditSettings](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Gantt.GanttEditSettings.html) component.

Segments can be merged by simply dragging a segment of taskbar and dropping it over another segment of same task.
