how to apply background color to group name in sap.m.List

[alagar_pandian]

Hi,

I am trying to apply background color for group name in the list as per the below screen shot.

I applied below css

.sapMList .sapMLIB.sapMGHLI {

height: 2rem;

line-height: 2rem;

font-size: 0.875rem;

font-weight: normal;

color: white;

background: #007cc3;

border-bottom: 1pxsolidrgba(0,73,144,0.33);

}

But background color for group gets changed only when hover over. Please suggest what can be done here.

Thanks
