Hi
I have been creating a front end form using tabs and group extensions, i found that the dashicons were not loading for groups or tabs as the css file were not being loaded on the front end of the site (by default in WordPress). So had to add in the wp_enqueue_style( 'dashicons' )
I assume this was missed from the tutorials? e.g. https://docs.metabox.io/extensions/meta-box-tabs/
Just letting you know so others who may have the issue are aware thanks, it would be great not to have to load this and is enabled when using front end forms extension by default.
