Firstly, you should decide for which menu location skin should be set.

In "Skin Options: location " you can change:

1. Background Gradient (Color) of the Primary Container.

You can choose and tune the background image for the primary container.

Notice: the background image replaces the background gradient and only flat color stays for the background.

3. Font for the first level items.

4. The size of icons in first level items.

5. Text Color of the First Level Item.

6. Text Color of the Active First Level Item.

7. Gradient (Color) of the background for the active first level item.

The process of setting up the gradient or color for this element is the same as for "Background Gradient (Color) of the Primary Container".

8. Background Gradient (Color) of the Dropdown elements.

The process of setting up the gradient or color for this element is the same as for "Background Gradient (Color) of the Primary Container".

9. Font of the dropdown menu item.

10. Text color of the dropdown menu item.

Set Of Installed Fonts

Select the fonts that must be included on the site. Remember that a lot of fonts affect on the speed of load page. Always remove unnecessary fonts.

Additional Styles (Different Colors for Each Menu Items)

Here you can add and edit highlighting styles. After that you can select these styles for menu item in "Menus -> Your Menu Item -> Style of This Item" option.

Custom Icons

You can add custom raster icons. After saving these settings, icons will become available in a modal window of icons selection. Recommended size 64x64 pixels.

Dashboard ► Mega Main Menu ► Specific Options

Custom CSS

This field is needed in the case when your template has a particular menu location and it needs adjustment. You can place here any necessary custom CSS properties.

Responsive for Handheld Devices

If this option is enabled, then the menu will be transformed, if the user uses the handheld device.

Coercive Styles

This option is recommended to use only if styles of the installed theme interfere with the proper display of Mega Main Menu. If this option is checked - all CSS properties for this plugin will have "!important" priority.

"Indefinite Location" Mode

If this option is checked - all menus will be replaced by the mega menu. This will be useful for templates in which are not defined locations of the menu.

Dashboard ► Appearance ► Menus

Toggle the item of menu which you want to set.

Definite Item Settings

1. Standard WordPress settings of the menu item.

We will leave out the explanation associated with standard WordPress settings of the menu item as they are very simple and understandable. We will consider opportunities of the Mega Main Menu instead.

2. icon of the current menu item.

3. Hide Text of This Item.

Use this option if you want to display the menu item without a text. For example, link to the home page can be displayed without a text, and only the "Home" icon can be left.

4. Disable Link of This Item.

Use this option if you want to set up the menu item without an active hyperlink. For example: it can be the title for the column in multicolumn dropdown menu.

Settings of dropdown menus

Notice: these settings can be adjusted only for the first level items of the menu, and the style of displaying all children dropdown elements will depend on these settings. All examples here - http://menu.megamain.com/wp-content/plugins/demo_dashboard_2.html.

1. Submenu Type.

2. Side for dropdown elements.

Just choose the side to which dropdown elements will unfold. For example: if you set "Drop To Right Side" for this option then dropdown will start at the left side of the initial element and go beyond it to the right.

3. Number of columns.

This option influences the number of elements in one line for "Grid Dropdowns", the number of columns in the "Multicolumn Dropdown" and "Widgets Dropdown".

4. Enable the full width for the sub-menu.

If you check this option the dropdown menu will be stretched to the full width of the primary container.

5. Dropdown Background Image.

Use this area to select and set parameters of the background image for the dropdown item.

Follow the next steps to update (reinstall) plugin, all these steps are important for the correct working of the plugin:

1. Deactivate and remove the old version (all settings will be saved);
2. Install the new version;
3. Go to "Mega Main Menu settings" page and save settings again (*important);
4. Clear cache of the browser (Ctrl + Shift + R few times on the page);
5. All done.

My menu structure loses some items (or options) when I save the settings.

Cause of this problem is small value of the "max_input_vars" option in the configuration of your server (host). You must increase value of the "max_input_vars". You must to set a value that is twice as large of the current value.

• Most hosts have the opportunity to change this value in the "Host Admin Area".
  Example:
  If currently you have max_input_vars = 1000
  You need to set max_input_vars = 2000 (or more)
  
  
• You can try to change this value using ".htaccess" file in root directory of the your site. Add one of these lines at end of ".htaccess" file.

  php_value max_input_vars 9000
  php_value suhosin.post.max_vars 9000
  php_value suhosin.request.max_vars 9000

  
  
• You can try to change this value using "php.ini". Add this line if you don't find max_input_vars

  max_input_vars = 9000

  
  
• If that does not help you, ask your host support "How can I increase the value of the max_input_vars for my site?".
  
  
• Also you can deactivate the options that you do not use to customize the menu structure. It helps reduce the number of options and reduce the load on the server. Example:
  - If you do not use option "Icon Of The Item" - disable it globally in the "Settings of the structure -> Icon Of The Item -> Disable".
  - If you do not use option "Description Of The Item" - disable it globally in the "Settings of the structure -> Description Of The Item -> Disable".
  
  The most unused options, you can try to disable them:
  - Description Of The Item.
  - Style Of The Item.
  - Visibility Control.
  - Dropdown Background Image.

My menu is displayed incorrectly in IE9 (or older)

• IE9 and older not supported Alpha colors.
  In order to fix it, use HEX "#2a6496" instead RGBA "rgba(42,100,150,1)".
  
  
• IE9 and older not fully supported Gradients.
  In order to fix it, use flat colors (#2a6496 > #2a6496) instead gradients (#428bca > #2a6496).
  
  
• Our plugin supports IE8, but only in safe mode, it means that all navigation functions is available but without 100% design matching. MicroSoft officialy stopped support of IE8 in April 2014 - http://www.microsoft.com/en-us/windows/enterprise/end-of-support.aspx. If the MicroSoft stopped supporting their product, all other programmers can also stop supporting it.

"Sticky" feature does not work on mobile devices.

"Sticky" feature does not work on mobile devices, because if you open the menu, you can not click on the last item, it will always be outside the screen.

If you understand that use sticky menu on mobile devices is bad practice, but you still want it - use this code in "Custom CSS" field.

#mega_main_menu.direction-horizontal > .menu_holder.sticky_container
{
	position: fixed;
	top: 0px;
	left: 0px;
	width: 100%;
	border-radius: 0px;
	z-index: 2000;
	line-height: 0px;
	text-align: center;
}
#mega_main_menu.direction-horizontal > .menu_holder.sticky_container > .menu_inner
{
	display: inline-block;
}
#mega_main_menu.direction-horizontal.include-logo > .menu_holder.sticky_container > .menu_inner > .nav_logo,
#mega_main_menu.direction-horizontal > .menu_holder.sticky_container > .menu_inner > .mega_main_menu_ul
{
	vertical-align: top;
}

{
	position: relative !important;
