## Description

**As** a developer  
**I want to** restrict the selection mode of the tree view to single select  
**so that** I can use the tree view for hierarchical selections, where only a single selection is allowed.

**Acceptance criteria**

**TreeView**

*   There is a new `select_variant` called `single`
    
*   This variant alows only one item to be selected
    
    *   If the tree view is set to single select and a user selects another item, the previous selected one must get deselected.
        
    *   The Tree View is still submittable via a form (submitting only one value)
        
*   In single-select mode, remove the possibility of adding the trailing icon.
    
    *   Instead, use that slot to indicate current select with a ✔ icon.
        

**FilterableTreeView**

*   If the tree view is set to single select, the filterable tree view must
    
    *   hide the "include subitems" option.
        
    *   hide the segmentedControl
        

**Technical notes**

*   Should we consider of NOT showing checkboxes? Should we maybe reuse the `current` state for the selection?
