Treeview

The Treeview component in vFlow 2.0 allows users to visualize hierarchical data in a collapsible and expandable format, which is useful for representing nested structures like file directories or organizational charts.

Key Features

• Node Representation: Each item in the Treeview is called a “node,” and nodes can have child nodes, forming a tree-like structure. This allows you to represent parent-child relationships between data elements.
• Collapsible Nodes: The Treeview component supports expanding and collapsing nodes, helping users manage large datasets by showing or hiding certain levels of detail.
• Dynamic Loading: The component supports dynamically loading nodes as they are expanded, which optimizes performance when dealing with large datasets.
• Searchable Tree: The component includes a search bar that allows users to quickly find specific nodes by filtering the tree based on keywords.

Common Use Cases

• File Management Systems: Ideal for displaying directory structures where users need to navigate and manage files or folders.
• Organizational Charts: Useful for visually representing hierarchies within an organization, such as departments, teams, and employees.
• Menu Structures: Can be used to design and display nested navigation menus in applications.
• Product Categories: Helpful for e-commerce platforms to show product categories and subcategories in a structured way.

The Treeview component enhances user experience by providing an interactive and visually appealing way to navigate and manage hierarchical data.

These settings allow you to tailor the Treeview to your specific design preferences and requirements.

Animation

This option allows you to apply several animations to enhance the component’s loading appeal. The following are the available animations:

1. Bounce
2. Flash
3. Pulse
4. Rubber Band
5. Handshake

Their Configuration:

1. Click the Type list, and then select an animation to apply an effect when the component loads.
2. After you select one of the animations (for example, Bounce), you will see the following configuration options:
   • Speed: In this field, you can select one of the following options to adjust the speed of the animation:
     • Faster
     • Fast
     • Slower
     • Slow
   • Delay: Click this list to select a value (for example, 3 seconds). This value specifies a time period. The application will load the animation after this time period (for example, 3 seconds).
   • Repeat: In this list, select a value (for example, 2). This value specifies the total number of times the application will play the animation.
     
3. After you configure the component’s animation properties, click to apply them to the component.

Events

The Events option of the Treeview component, as shown in the image, allows you to assign task groups that will execute when specific actions occur within the Treeview component. These tasks can be created separately in the configurator or inventory and can be grouped to perform various actions when certain events are triggered.

Here’s a breakdown of the Events section:

1. On Node Click:
   • This option allows you to assign a task group to be executed when the user clicks on the Treeview component’s Node.
   • You can select an existing task group from the dropdown list labeled Select Task Group or go back to the inventory or configurator to make a task or task group if needed.
2. On Load:
   • This option lets you assign a task group that will execute automatically when the Treeview component is loaded.
   • This could be useful for initializing data or triggering other actions as soon as the Treeview is displayed.
3. Custom Load:
   • The Custom Load event enables you to trigger a specific task group during a customized loading scenario.
   • Similar to the previous options, you can choose the task group to be executed from the Select Task Group dropdown list or go back to the inventory or configurator to make a task or task group if needed.

After assigning the appropriate task groups to these events, click the button to apply your configuration to the Treeview component.

In summary, the Events section provides flexibility in automating actions within your Treeview component by linking predefined tasks to occur on user interaction (e.g., clicking a node) or during the Treeview’s loading by linking predefined tasks to occur on user interaction or during the Treeview’s loading process. This customization ensures a more dynamic and interactive user experience, tailored to your application’s specific needs.
