Multinode Treepicker not showing selected items in tree

Which Umbraco version are you using? (Please write the exact version, example: 10.1.0)

13.2.0

Bug summary

The multinode treepicker doesn't show selected nodes when browsing for new nodes

Specifics

We've had complaints from some editors because once browsing through the nodes in the tree picker it's you can't directly see what has already been selected.

Although selecting a node again doesn't necessarily cause a problem as it just remains in the list. The interaction here feels slightly unexpected.

Steps to reproduce

1. Create a Mutlinode Treepicker (for a minimal example I just selected a single allowed node type)
   

2. Add this picker to a document type

3. Select some items and submit (you can save if you want, but doesn't matter).

4. Reopen the selection
   

Expected result / actual result

It would be much clearer to editors if the items they already had selected appeared with a check next to them like when in the editing state.

Hi there @anthony-3chillies!

Firstly, a big thank you for raising this issue. Every piece of feedback we receive helps us to make Umbraco better.

We really appreciate your patience while we wait for our team to have a look at this but we wanted to let you know that we see this and share with you the plan for what comes next.

• We'll assess whether this issue relates to something that has already been fixed in a later version of the release that it has been raised for.
• If it's a bug, is it related to a release that we are actively supporting or is it related to a release that's in the end-of-life or security-only phase?
• We'll replicate the issue to ensure that the problem is as described.
• We'll decide whether the behavior is an issue or if the behavior is intended.

We wish we could work with everyone directly and assess your issue immediately but we're in the fortunate position of having lots of contributions to work with and only a few humans who are able to do it. We are making progress though and in the meantime, we will keep you in the loop and let you know when we have any questions.

Thanks, from your friendly Umbraco GitHub bot 🤖 🙂

Hey Anthony
After evaluating this report I have come to the conclusion that this is not a bug report but a feature enhancement request.
The UI in question indicates that when clicking on the ADD button, an interface will be shown where you can ADD items to the current selection.
Changing the behavior of this picker would also, for example, have to take into account what happens when a preselected item is deselected.
Because of this I am going to change this issue into a discussion.
