Is MultiSelect possible with the Checkbox Tree? (App Designer)

The normal tree app component has the MultiSelect property. The checkbox tree (introduced in 2021a), however, has not and, so far, I have not been able to enable the selection of multiple child nodes of the checkbox tree. Is it possible to circumvent this limitation?

I tried to reproduce your issue but couldn't. In MATLAB 2021a, I am able to create a checkbox tree where I can select multiple child nodes. Can you add some more details about the issue that you are facing?

You can refer to the documentation for more details

I thinks he is referring to selected nodesI cannot select multiple nodes, either. I can just check/uncheck them but I want to select them. Is there a reason the MultiSelect property is not implemented for checkboxtrees?

In MATLAB 2022a this is still not possible. Setting the SelectedNodes property to multiple nodes gives the following error:

'SelectedNodes' must be an empty array or a 1-by-1 TreeNode object that is a child in the CheckBoxTree.

In Matlab 2023b it is still not possible

[Markus Leuthold]

Still not possible in Matlab 2025b

>> hTreeRoot.SelectedNodes = hTreeRoot.Children(1:3)
'SelectedNodes' must be an empty array or a 1-by-1 TreeNode object that is a child in the CheckBoxTree.
