![]() With this dynamic data loading approach, only after the user expands a node, the children for that particular parent node will be retrieved. The Ignite UI for Angular IgxTree can be rendered in such way that it requires the minimal amount of data to be retrieved from the server so the user could see it as quickly as possible. Shift + Click - when performed on the node checkbox, toggles selection of all nodes between the active one and the one clicked while holding Shift if selection is enabled.Click - when performed on the node checkbox, toggles selection of the node if selection is enabled.Since both selection types allow multiple selection, the following mouse + keyboard interactions are available: When selection is enabled, end-user selection of nodes is only allowed through the rendered checkbox. * - expands the node and all sibling nodes on the same level.If the node has link in it, open the link Shift + Space - toggles selection of all nodes between the active one and the one pressed Space while holding Shift if selection is enabled.Space - toggles selection of the current node.Shift + Tab - navigates to the previous focusable element on the page, outside of the tree.Tab - navigates to the next focusable element on the page, outside of the tree.End - navigates to the LAST visible node.If on a collapsed parent node, expands it. Arrow Right - on an expanded parent node, navigates to the first child of the node.If on a child node, moves to its parent node. Arrow Left - on an expanded parent node, collapses it.Ctrl + Arrow Up - navigates to the previous visible node.Arrow Up - navigates to the previous visible node. ![]() Ctrl + Arrow Down - navigates to the next visible node.Arrow Down - navigates to the next visible node.The IgxTree navigation is compliant with W3C accesibility standards and convenient to use. This functionality is enabled by default and allows users to navigate through the nodes. Keyboard navigation in IgxTree provides a rich variety of keyboard interactions for the user. In this mode, a parent node will go into the indeterminate state when some but not all of the child nodes are checked. The TreeView checkboxes also have a tri-state mode, which is applicable only for partially selected parent nodes. The Angular Tree component provides built-in support for checkboxes, allowing users to select more than one item. When a parent has some selected and some deselected children, its checkbox is in an indeterminate state. In this mode a parent's selection state entirely depends on the selection state of its children. This will render a checkbox for every node. To enable cascading node selection in the igx-tree, just set the selection property to Cascading. Each node has two states - selected or not. To enable bi-state node selection in the igx-tree just set the selection property to BiState. Users cannot select or deselect a node through UI interaction, but these actions can still be completed through the provided API method. In the igx-tree by default node selection is disabled. Below we will take a look at each of them in more detail. This property accepts the following three modes: None, BiState and Cascading. In order to setup node selection in the igx-tree, you just need to set its selection property. The next step is to import the IgxTreeModule in your app.module file. In an existing Angular application, type the following command: ng add igniteui-angularįor a complete introduction to the Ignite UI for Angular, read the getting started topic.
