ComboBoxAdv with multilevel checkbox tree

[Tech Shop]

I need a solution to have a ComboBoxAdv with the AllowMultiSelect option enabled. Have several levels as a tree. It's possible? I tried to find a solution in the documentation, but did not find it.

Attachment is a better explanation with images.

Hi Tech, 

  

Thanks for getting in touch with Syncfusion Support. 

  

With ComboBox, we reviewed the recorded requirement and understood that you would like to add the TreeViewAdv to the ComboboxAdv control as a drop-down content. We prepared a workaround by changing the ComboBoxAdv control template to add TreeViewAdv to it as a child and binding the SelectedItem of TreeViewAdv to the content of ComboBoxAdv. Please find the sample from the below attachment. We have also attached the sample for your reference. Please download it from following link:

Please try this solution and let us know if it meets your requirement.
