Collapsed Category in Blocks when Grapes Editor is loaded

Try with this

const categories = editor.BlockManager.getCategories();
categories.each(category => {
	category.set('open', false).on('change:open', opened => {
		opened.get('open') && categories.each(category => {
            category !== opened && category.set('open', false)
        })
	})
})

Wow man, Thanks a lot!

Give your custom class and set styles with the background image Eg Code:

In bm.add block

attributes: {
  class: 'custom-icon flowz-callToAction-style-2',
  title: 'Style 2',
},

and in CSS

.custom-icon {
  padding:0 !important;
  width:100px !important;
  height:50px !important; 
  min-height: auto !important
}
.flowz-callToAction-style-2{
  background:url(screenshots/callToAction/2.jpg) no-repeat;
  background-size:100% 100%
}
