Store Locator Plugin Guide
Agile Store Locator for WordPress has the click event on the list and the marker as default however in case some user wants to implement mouseover, it can be done quickly via adjusting the shortcode attributes, in this regard, we have provided two separate shortcode attributes the first one is for the store list and second is for the marker, as given below in the shortcodes.
Changing the store list's behavior to show the marker on the mouseover can be done with the mouseover_list shortcode attribute.
The mouseover behavior on the store markers on Google Maps can be applied via the mouseover shortcode attribute.
Combining them together will be as follows.
[ASL_STORELOCATOR mouseover_list="1" mouseover="1"]
