Admin Menu Editor plugin – Open Custom URL in New Tab

/**

 * Opens specific WordPress admin menu items in a new tab.

 * Handles both top-level items (by ID) and submenu items (by parent ID and text).

 ******

 * HOW TO USE:

 *

 * 1. Import the code Snippet.

 * 2. **IMPORTANT: CONFIGURE THE TARGETS (Choose ONLY ONE method):**

 *

 * **Method 1: Target a TOP-LEVEL Menu Item**

 * - Find the unique ID of the top-level menu item's <li> element.

 * - Replace the empty string in `var topLevelTargetId = '';` with that ID.

 * - Ensure `var submenuParentId = '';` and `var submenuTargetText = '';` remain empty.

 *

 * **Method 2: Target a SUBMENU Item**

 * - Using Code Inspection find the unique ID value of the top-level parent menu item's <li> element.

 * - Replace the empty string in `var submenuParentId = '';` with that ID value.

 * - Find the exact TEXT content of the submenu item you want to open in a new tab (i.e. the "Name" assigned to the submenu button - in my case it was 'PageSpeed Insights'.

 * - Replace the empty string in `var submenuTargetText = '';` with that text.

 * - Ensure `var topLevelTargetId = '';` remains empty.

 *

 * 3. Set the snippet to run on "Admin Area Only".

 * 4. Save and activate the snippet.

 * 5. Clear any WordPress caching and refresh your admin page.

 * 6. Test to ensure it's working. If yes, feel free to delete this top message block
