Selective Sync allows you to save individual settings for a new global library item. You can selectively sync any or all of the Content, Design, or Advanced tabs.

This is especially useful if you are delving into the Design or Advanced Tabs and would like to use your unique styles for multiple modules on your website while at the same time adding unique content in the Content tab for each.

A simple example would be to create a uniquely styled Header Module that is added to every page on your website.

In this example, you may want to have a unique combination of Design Settings shared across your entire website, but at the same time, you need to be able to add unique title text to each module to represent the current page. In this example, choosing to selectively sync only the Design Settings makes the most sense.

Only the options that you have selected will be editable within the library. When you add the global library item to your page, only the settings you have checked to be synced will be present.

Whenever you edit a global module, you can easily identify which options are synced by the sync icon's green color. Green icons are options that are currently being synced within the global module. Red means the item isn't synced.

All instances of the global item share options are edited with the green (enabled) sync icons.

Using Selective Sync in combination with global modules can be extremely powerful. Let's dig a little deeper.

Let's say you have a Fullwidth Header module at the top of your pages. This is quite common.

Each header module has a different title in the Content settings to represent the current page. You have also used the Design settings to give your header a unique look by adjusting the title font style to Bold and all Caps, and you have increased the Custom Padding on the top and bottom of the header to make the header module larger.

You want your header modules on each page to use this unique style, but you need each page to have unique titles.

In this case, you can create a Global Fullwidth Header module and selectively sync only the options in the Design tab.

Now, whenever you add this global module to a new page, the Design settings will be synced, but your Content settings will remain unique for the current module. If you ever want to change the style of the headers on all your pages, you can modify the synced Design settings shared by these global modules and the changes will be reflected on every single page that the global header has been used!

This same theory could be applied to the Advanced tab as well.

Let's say you created a Slider Module and used the Advanced tab to apply a unique animation to the slider's button.

You want to use this new, unique animation on all of the Slider Modules on your website. In this case, you can create a new Global Slider Module and selectively sync the Advanced settings, including your custom CSS animation.

Add this slider to your page and adjust the Content and Design settings freely while keeping your unique Custom CSS synced across the entire series of modules. If you ever want to adjust the Advanced settings for this series of global modules, you only have to do it once.

Editing the Advanced settings in one module updates for all implementations of this Global Slider Module.
