Hi Sasi,

Which version of PRPC you are using.

Can you please share configuration snapshot for the layout(tab and column repeat), any container format used in tab configuration?

Hello Sasi, 

Thanks for raising your query on PSC.

Could you share the information as Shibani requested.

Assuming you are using Pega 7.1.8, from the screenshot, I understand that you have set the tab border( as say style: solid ; color: blue). If  yes, is it possible not to set the border styles for the tab control. 

Also, are you using/set responsiveness feature on the column repeat control? This is to understand when you say the border is not expanded dynamically. I see that this feature is not available under tab control's skin.

Regards,

Rincy
