Itried to built a menu to add to a panel in every pages of my app. I have a custom component wich contains a grid with 2 column and 7 rows. For each row i have an icon and a label and on a click event on the cell that contains the label there is a navigation to a specific page. I added the custom component to a panel in each page of my project. I would like to color the row of my custom component that has been clicked by a user before to navigate to a page. How can i obtain this result?
