The tree structure allows you to manage nested hierarchical structures of items, such as the portal header menu and cards. This functionality is intended to reduce work efforts spent on the portal structure configuration. The nested portal items can be managed through a special tree-like structure, making this process easier and more effective.

Use the tree structure to create a node hierarchy with any predefined nesting level that allows you to implement the navigation structure on a portal. 

Note

It is recommended to recreate portal elements (headers and cards) using the tree structure if you are using the customized ones. Otherwise, the errors may occur in the portal header or cards functionality.

A scheme below illustrates the functionality work principles:

Configure a tree structure


To configure a tree structure from scratch, follow the steps below:

  1. Configure a node type.
  2. Configure a tree structure.
  3. Create a node itself and configure its attributes.

Excerpt

Node form fields

FieldMandatoryDescription
Title+Specify the node title. This field can be populated in any language supported by the platform.
Tree+

Select a previously created tree containing information about the structure.

Tip

You can use the "out-of-the-box" tree. It is called Portal Header Menu and is stored in the Tree (simple_tree) table 

Info

First, fill in this field, so the General tab with the tree attributes appears.


Active-Select this checkbox to make the node active or inactive.
Order+Enter a number to define the node order. The nodes are sorted in ascending order.
General tab
Access criteria-Specify the user criteria defining user access to this node (a card or a header element). If no criteria selected, all users are allowed to use this element and its sub-elements as long as the separate criteria do not protect them.
Node type-Specify a node type by choosing from the previously created ones.
Nesting level+

Node nesting level. This field is populated automatically.

This parameter shows on which nesting level this item is located.

Parent-

Specify a parent item if you are implementing a structure with some nesting levels, like this:

Code Block
languagetext
themeEclipse
titleStructure
* Parent item 1

** Child item 1

** Child item 2

** Child item 3

* Parent item 2

** Child item 4

** Child item 5


Extra Attributes tab

This tab appears if the used node type has the RE model specified, and the Need URL attribute of the node type is enabled.
URL+

Specify a URL for an item. In this field, you can specify either absolute or relative URL (relative to the current portal referring to the tree to which the current node is assigned):

Info

Absolute URL: https://instance.example.com/portal/profile

Relative URL: /profile




Tip

When a node is created, you can create child nodes for it. You can do this right from its record form by completing the steps:

  1. Scroll down to the Child nodes related list.
  2. Click New and fill in the fields as described above.
  3. Click Save or Save and exit to apply the changes.
