Change the Underline Color ony

Hi Poojara_D12 ,

As i know, Power Bi Buttons do not have accent bar in their styles, underline come with text, thats why when you change the color of text affect the underline as well.

But, you can achieve the same results using power bi page navigator and enable the Accent Bar under styles as shown bellow:

Hi Poojara_D12 

You can simply add shape > horizotal line

Same requirement I ahve implemented with Shape horizontal line.

I have to add same to each page navigation option. so when you naviagte you underline option will be displayed.

other option is Accent bar with bottom option

I Hope I answered your question!
