  • Follow the installation steps:


Step 1: Installation

LoginPluginsAdd newUpload in .zip formatBrowse the installerInstall buttonActivate
After the activation you should see two plugins, the Nextend and the Nextend Smart Slider 2

Step 2: Create a new slider

Now you can start using the Smart Slider 2 in the left sidebar:

Creating quick slider

The fastes and easiest slider to create is quick slider. Click on Start and begin the creation of your slider. Take a look at the video tutorial:

Or follow these instructions:
On the bottom of the page you will see the add image option. Use that to pick your images for the slider.

If you don’t like the order, or you want to remove one image, then you can drag and drop the images, change their order or delete them. If you click on generate now, then you will have your slider ready, but here are the other options you can change before you do that:

Quick slider configuration
  • Slider name – The name of the slider
  • Slider size – The size of the slider (It will be responsive)

The Canvas size here doesn’t matter. It will only matter if you will want to modify your slider type to one of the accordions.

Animation Settings
  • Animation – Basic sliding animations
  • Properties – The duration, delay and easing of the sliding. If the parallax is lower then 1, then the next slide will start before the other is finished, and the sliding is very interesting this way.
  • Background animation – If you turn this on, then only the here selected animations will be applied, the basic sliding animations won’t.

Choose slider preset and layout

The slider preset are predefined widgets on the slider, like arrows, bullets, etc..
The layout is how the image and texts will show up on the slider.

Step 3: Publish your slider

You can publish the Smart Slider 2 in three different way: via the widget control panel or by shortcode and of course you can add it to your template files too via PHP.

  • Widget control panel: Go to AppearanceWidgets, drag the Nextend Smart Slider 2 widget and drop it into one of your Widget Area. Here you can add a Title and you can choose from your previously created sliders. Finally press the Save button and enjoy your awesome slider!
    Note: You can also choose custom sliders for tablets, and mobile phones.
  • smart_slider_widget

  • Shortcode:
    1, If you click on your slider’s name, then you can see the shortcode of your slider, which you can copy and paste wherever you would like to use it, in pages and posts.

    2, If you go into a page or a post site and switch the editor to Visual view, then you can see our icon. Click on it and choose from the existing sliders.
  • post_page_visual

  • PHP code: If your theme doesn’t has a good position for your slider, then you will need to hardcode it into one of your theme’s php files. All you have to do is, use the WordPress’ do_shortcode function to put our shortcode in there. You can see here how it should be, just change the ID to your slider’s, and you can paste it into your php file:
    <?php echo do_shortcode('[smartslider2 slider="2"]'); ?>
  • Shortcode and PHP code with custom tablet and mobile phone sliders:
    If you would like to have custom sliders in your site for tablets and phones, this is what you should do:
    1, Go to your sliders, and get your shortcodes.
    2, Check the id of your sliders. It’s the number after the equal sign.

    For example:

    Main slider: [smartslider2 slider=”1″] -> id:1
    Tablet slider: [smartslider2 slider=”2″] -> id:2
    Phone slider: [smartslider2 slider=”3″] -> id:3

    3, Insert the id-s into this shortcode: [smartslider2 slider=”1″ tablet=”2″ phone=”3″]
    4/1, Now you can go to your post or pages, and put this shortcode in.
    4/2, For hardcoding your sliders into your theme files this is how your code should look like:

    <?php echo do_shortcode('[smartslider2 slider="1" tablet="2" phone="3"]'); ?>

    Options for this shortcode:

    • If you don’t want other slider, then the main one, then write -1 to it:
    <?php echo do_shortcode('[smartslider2 slider="1" tablet="-1" phone="-1"]'); ?>
    • If you don’t want any slider for tablets or mobile phones write 0:
    <?php echo do_shortcode('[smartslider2 slider="1" tablet="0" phone="0"]'); ?>
    • Or you can mix it:
    <?php echo do_shortcode('[smartslider2 slider="1" tablet="-1" phone="0"]'); ?>
    <?php echo do_shortcode('[smartslider2 slider="1" tablet="2" phone="-1"]'); ?>
