Layer6

If you wish to have a layer slider like we have on our demo sites, the easiest way is to import the slider Demo Content (surely, that is possible only in case the Layer Slider is represented on demo site).

For import please see the DEMO CONTENT folder in the archive you have downloaded and find the Slider demo content there. Please follow the import instructions listed in a readme file. After you have imported the slider, you will have all the slider settings like we have on our demo, as well as the captions. You will only need to add your images for background.

The instructions below are just sample instructions that will give you a basic idea about how to manage the slider.

To configure Layers click this button:

To upload image for a Sublayer just click on the empty field beside the image placeholder:

Layer10

Layer11

Use H1-H6 tags to enter some text for a capture, add a link using Link tab, etc.
Drag the elements in the "Preview" area to get the perfect look.

This slider's option is the most important - a slider Shortcode:

Each slider has its own shortcode. You will use it to add the slider to the WYSIWYG Content Composer.
