To create image tabs, set the data-image-tabs attribute to "true". Works with horizontal and vertical tabs.
<div data-wm-plugin="tabs"
data-source="/portfolio"
data-tab-images="true"
></div>
You can adjust some of the padding around the images with this Custom CSS:
/**
* Tabs Plugin
* From Will-Myers.com
* Stacked Image Tabs
**/
div.wm-tabs {
--tab-button-padding-y: 12px;
--tab-button-padding-x: 12px;
}
