Hi,

Having a scrollTo method, similar to the one in the Grid component(API), would be a very useful feature for the TreeView component.

Hello,

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

Since the itemLookup as the selectedKeys works with index and is not able to search the tree by a key value, which in my opinion is really a must-have feature for the tree.

It would be by far easier if we could have a method findParentsByKey and findParentItemsByKey and define a key and values and get the full results.

Like for example

findParentsByKey(id,  123)  - this could return an array of objects of the key/values of the parents of the node with id: 123.

findParentItemsByKey(id,  123) - return only the parent nodes (only those with children), an array of objects with the key/values of each parent item.

When you have a very long list of items to display in the tree view its not always ideal to have a vertical scroll.  In order to better utilize space and allow for the user to see more options on the screen at once it would be nice to have a configuration to allow for the list to be split up into columns.  So for example if you have a list of 90 items, you can maybe have 3 columns of 30 items each.  Please see the attached image that demonstrates what I am referring too.  

 

The Kendo Silverlight does have something similar: https://docs.telerik.com/devtools/silverlight/controls/radtreeview/how-to/create-horizontal-treeview

Request related to - https://github.com/telerik/kendo-angular/issues/3452

Currently, the default filtering mode, known as "lenient", halts its search as soon as a match is identified, showcasing all child elements of that match irrespective of their correspondence with the filter term. However, due to this design, using "lenient" mode while simultaneously auto-expanding child elements matching the filter term is not feasible.

In the "lenient" mode, the algorithm terminates its comparison upon encountering a match. Consequently, utilizing "lenient" mode along with automatic expansion of potential child matches requires switching to the "strict" filtering mode. This compels the algorithm to perform comprehensive comparisons throughout the entire tree, ensuring explicit identification and expansion of all matches.

https://stackblitz.com/edit/angular-5oxrjd-m3qsi6?file=app%2Fapp.component.ts

An enhancement can be introduced by incorporating a setting that drives the algorithm to perform exhaustive comparisons even within "lenient" mode, introducing the capability to expand matches while maintaining the current operational design.

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.

Hi,

 

  We are facing a notable poor performance in tree view when loading about 1500 tree nodes with custom template and it is taking approximately 32 Seconds to load it. You have already provided load more option to virtualize data but this is not so user friendly and suggested listview which has virtualization also not good fit to replace treeview.  I wonder how this virtual scroll is missed in tree view!!. It is very important component to our project If you could provide this feature will be great.

 

Thanks& regards,

Ramesh M

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 adjust the drag and drop sensitivity, by requiring more mouse movement before the drag event is fired.

[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.

Currently, the TreeView has a focus event for the component. However, when the focused node is changed programmatically using the focus method,  there is no event. Can we have a built-in event for this?

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

Hello,

 

We would like to be able to customize icons used in kendo-treeview (ex: arrows to access child elements).

This is required to match the rest of our style guide where we only use fontawesome icons.

Having still some kendo UI icons feel a bit weird at the moment.

 

Thanks!

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

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
