This diff removes the arrow icon from the WordPress admin menu. Let'…

…s break down the changes:

• src/wp-admin/menu-header.php: The primary change is the removal of the $arrow variable and its inclusion in the menu item's HTML. Every instance of $arrow within the <a> tag has been deleted. This directly removes the arrow element from the rendered output.

• src/wp-admin/css/admin-menu.css: The CSS changes further support the removal of the arrow. The rules related to .wp-menu-arrow are removed. Specifically:

  • #adminmenu li.wp-has-current-submenu a.wp-has-current-submenu, #adminmenu li.current a.menu-top, #adminmenu .wp-menu-arrow, #adminmenu .wp-has-current-submenu .wp-submenu .wp-submenu-head, #adminmenu .wp-menu-arrow div is changed to remove .wp-menu-arrow and .wp-menu-arrow div. This removes styling for the arrow itself and for parent menu items.
  • The /* A new arrow */ comment block and the following .wp-menu-arrow style block, which hid the arrow (display: none !important;), is completely deleted. Since the arrow element is no longer present in the HTML, these styles are unnecessary.

In summary, these changes effectively delete the arrow that typically appears next to WordPress admin menu items that have submenus. The HTML generating the arrow is removed, and the corresponding CSS styling is deleted. This results in a cleaner, more minimalist look for the admin menu.
