synergyit Hi
Try add this to custom.css file :
.nav-child .divider{overflow: visible !important;height: auto !important;background-color: #fff !important;margin-left: 10px !important;}
Finding custom.css or you may create a new file with similar name (if it doesnt exist) ::
JA Simpli ship with an empty custom.css file in the /css/ subdirectory of your template. Simply add your styles to this file and they will be included in your layout.
