+## Customize Nodes
+
+TreeViewAdv provides customization options to control the appearance and behavior of nodes with visual elements such as lines, expand/collapse buttons, checkboxes, and option buttons.
+
+### Root Lines
+
+Display connecting lines between nodes using `ShowRootLines` and `ShowLines` properties. Both are set to `true` by default.
+
+When `TreeViewAdv.ShowLines` is set to false, the connecting lines will not be displayed for the entire control.
+
+```csharp
+// Hide connecting lines
+this.treeViewAdv1.ShowLines = false;
+```
+
+### Plus/Minus
+
+We can display Plus/Minus sign for the parent nodes by setting the property `TreeViewAdv.ShowPlusMinus` to True. This will set Plus/Minus sign for all the parent nodes in TreeViewAdv.
+We can also set this for nodes using `TreeNodeAdv.ShowPlusMinus` property in the `TreeNodeAdv`.
+
+The nodes in the `TreeViewAdv`, even when it is in the expanded state, can still display the Plus sign using the `TreeNodeAdv.ShowPlusOnExpand` property. `TreeViewAdv.LoadOnDemand` property should be set to true for this feature to be effective.
+
+```csharp
+this.treeViewAdv1.ShowPlusMinus = false;
+```
+
+### CheckBox
+
+We can display CheckBox for all nodes in `TreeViewAdv` by setting `TreeViewAdv.ShowCheckBoxes` property to `True`. The CheckBox for individual nodes can also be shown or hidden using `TreeNodeAdv.ShowCheckBox` property in `TreeNodeAdv`.
+
+```csharp
+this.treeViewAdv1.ShowCheckBoxes = false;
+treeNode.ShowCheckBox = true;
+```
+
+### OptionButton
+
+The Option Buttons can be displayed for the nodes in the `TreeViewAdv` using the `TreeViewAdv.ShowOptionButtons` property. We can also show or hide the Option Button for individual nodes using `TreeNodeAdv.ShowOptionButton` property in the `TreeNodeAdv`.
+
+```csharp
+this.treeViewAdv1.ShowOptionButtons = false;
+treeNode.ShowOptionButton = true;
+```
+
+### Assigning Active Nodes
+
+The `TreeViewAdv.ActiveNode` property holds the currently selected node. By default, it is `null` when no node is selected.
