[Share] Inverse Selection of Visible Top-Level Items

[bloomingseed]

Description

This script selects all visible top-level items in the Zotero library that are not currently selected. Useful for bulk operations where you want to toggle or invert the current selection (e.g., tagging or deletion).

• Selects only on top-level (non-child) items.
• Ignores collapsed/hidden or child items.
• Perfect for quickly toggling selections across filtered or sorted item lists.
• Works in all views:
  • Standard collections
  • Saved searches
  • Trash bin (with caveat: won't select deleted collections)
  • Group libraries

// === 1. Initialize ===
const zoteroPane = Zotero.getActiveZoteroPane();
const itemsView = zoteroPane.itemsView;

// === 2. Get Selected Item IDs ===
const selectedIDs = items.map(item => item.id);

// === 3. Get All Visible Top-Level Item IDs ===
const itemRows = itemsView._rows;
const allVisibleTopLevelIDs = itemRows
    .filter(row => row.ref && !row.ref.parentItem)
    .map(row => row.ref.id);

// === 4. Compute Inverse IDs ===
const inverseIDs = allVisibleTopLevelIDs.filter(id => !selectedIDs.includes(id));

// === 5. Select Inverse Items ===
itemsView.selectItems(inverseIDs);

Anything else

P/s: To tag the newly inversely selected items, use the companion script for adding a temporary random tag to selected items: #509.
