I am looking forward to add custom options to Menus block in wordpress.
For e.g. When we add a menu item,with menu manager in WP, there are few text boxes appear inside the collapsible panel, such as Title, Label, etc.
I want to add a custom option of mine into the menu items, by developing a plugin.
I went through the core code, but couldn't find any hook, that could be available to accomplish this.
