jQuery | menu-aim plugin

jQuery provides menu-aim plugin that helps programmers to develop effective dropdown menus along with easy navigation of sub-menu contents. The plugin can very well differentiate between user hover on dropdown items vs navigation of submenu content. The plugin also supports JS event handling functions like mouse enter or exit, activate or deactivate of submenus.

Please download menu-aim plugin and save the required files in your working folder. Include the required files in the head section of your code as shown below.

Example 1: In the following example, the menu-aim plugin is demonstrated that results in a dropdown menu. The dropdown menu have HTML un-ordered list with list items depending on the requirement. Each list-item has submenu “div” with title and content. The HTML structure for the dropdown menu is implemented by using menu-aim plugin’s CSS and JS codes. Other functionalities like “activateSubmenu” and “deactivateSubmenu” is also provided by the plugin itself. The programmer can change or enhance the JS code as per the application’s requirement.

Output:

Example 2: In the above example, each list-item has submenu with its “title” and “content” which was shown in a simple manner. The following example demonstrates, how to add another side-sub-menu by using HTML “ul” and “li” elements and classes provided by menu-aim plugin. Each side-sub-menu has list-items with links to the respective title topics, just for a basic understanding of submenu.

Output:

Example 3: The following example demonstrates the use of menu-aim plugins javascript functionalities. It shows the simple implementation of various option settings and functions. For example, if the user enters the submenu, the background color is changed to “red” and after leaving the main dropdown menu, a message is shown at the top of the dropdown. The programmer can write code for other options as per the application requirement.
