react-flat-treeview

Visual representation of a dynamically loaded tree with very long, flat branches.

The items are managed by the parent component, but the state of the tree itself (which items are closed / open / selected) is managed by the tree component. The loading state is managed by the parent component as well (this allows for the data to be reactive)

Props

• branches: an object where the keys are the categories, and the values are list of items for that branch. Each item has the following properties:
  • branches: sub-branches for that item. An object where the keys are the categories, and the values are the list of items for that branch.
  • title: string to display for the item
  • id: a unique identifier for the item (among this branch). Each id must be unique for the item's category, though it may be repeated in different categories.
  • loading: indicate the content of that item (its children) is currently loading from the server
• categoryLabels: map category name to labels
• onItemSelected: a function that will be invoked when the user selects an item.
• onOpenItem: a function that will be invoked when the user opens an item. This should trigger a loading mechanism for that item. The function will be called with the category key, and the item (the item should not be modified directly)
• children: the component's child will be used as the detail view, when a user selects an item

Example

See the example app to view an example of how the component could be used in your own app. This can be run after you clone the repository by running npm start
