My suggestion for the Angular treeview is to expose a doubleClick event, as opposed to just the single click event (or the selection node event).
This would help in preventing events from firing unless the user has double clicked a node (as an option).

Provide an option to specify the drag target.

Currently, we can click anywhere on the item and drag it. But there are scenarios where the items should be draggable only when clicking an icon.

[isDisabled]="disabled || isDisabled(node, nodeIndex(index))"

Because of the hardcoded disabled property, isDisabled cannot be reliably used to control which item is disabled.

Disabling the parent node automatically disables the entire tree under it and isDisabled is never called for those items.

It should behave like other functions - isChecked, isExpanded, isVisible etc - where you have full control over which item does what.

Hi,

Please provide a property that can be used to associate the node pageSize with a specific property of the data items.

thanks

Hi,

Please provide an option that allows exposing the TreeView nodes' indexes. Such a feature will be especially helpful when rearranging the TreeView nodes by dragging.

Thank you

Hi,

 The tree view enables us to drag and drop one item at a time. we have a scenario where i want to drag and drop multiple items. tree view also enables multiple selection of items but not supporting drag and drop of multiple items. Could you please provide some solution to dag and drop multiple items

Please provide an optional callback function when rebindChildren has finished and the tree is stable again.

Thanks

Hi,

I was going through Treeview in angular 5.
What I feel lacking in Treeview is search functionality.

I would be very thankful if you can provide search functionality.

Thanks

Hello,

Do You have plans, to provide extended 'desktop-like' multiselection of nodes with ctrl/meta or shift key pressed?

It would be useful if the TreeView can support the Angular Routing feature, for example allowing to set a RouterLink directive for each item of the tree.

support r-click menu

Add the posibility to expand all nodes in a TreeView component.

Hi , 
When can we expect RTL support for Treeview component? 

Thanks
