[slplus] is the primary shortcode used within WordPress sites to display the Store Locator Plus map and location search interface. Many other attributes can be found within the plugin and add-ons.
A shortcode is a special label inside of square brackets that is used within WordPress pages and posts to display the output from a plugin. You place a shortcode within the text of your page or post and the plugin will “do it’s magic”.
Note: As of WordPress Plugin API update 4.2.3 effects shortcodes with filtered styles which will not be recognized when stored between quotes.
