Used Filter Bulk selections
The new "Bulk selection" button has a tool-tip "Bulk selections" and allows the selection of the currently displayed (child) list or one or several levels in the hierarchy through a new popup. The popup only contains the list of the really available levels depending on the hierarchy of the codelist and on really selectable items (with data). If there is no hierarchy (all items are at the root level) then the popup has only one entry 'Entire currently displayed list'.
When selecting the 'Entire currently displayed list' then all its individual items are marked as selected and added in the "Used filters".
The 'Entire hierarchy level' selections also mark the individual items as selected but they are displayed in the "Used filters" using combined groups:
When the user deselects any of the items in a complete level selection then in the Used Filters this group is replaced by the list of individual items.
The UI design mockups contain some examples. They should be updated with the new "Bulk selection" design.
