Clipboard Manager for Elementor enhances Elementor’s built-in clipboard with a multi-item stack. Every time you copy a widget or container, it’s added to your clipboard history. Select any item (or multiple items) and paste them with Ctrl+V / ⌘V — just like Elementor’s native clipboard, but better.
<h4>Features</h4>

<li>Multi-item clipboard stack — automatically captures every Ctrl+C / ⌘C</li>
<li>Native clipboard compatibility — Ctrl+V / ⌘V pastes the selected item(s), no workflow changes</li>
<li>Floating panel — draggable, resizable dialog; can be stacked below Elementor’s Structure panel</li>
<li>Multi-select paste — Ctrl+Click / ⌘+Click to toggle, Shift+Click to select a range, paste them all at once via Ctrl+V / ⌘V or the header paste button</li>
<li>Rename items — double-click to rename for easy identification</li>
<li>Persistent storage — items survive page reloads (localStorage)</li>
