Thank you for reaching out to us here. It can be achieved by adding a custom link to your menu. Go to Appearance > Menus > edit your menu which is assigned to primary menu > add a “Custom Links” type of menu item > in the URL input field, enter:
ID_element_target with the ID name of “What Our Clients Say” row. The easiest way to find it is by using the web browser’s inspector tool. On Firefox, it can be activated from right click > Inspect Element > move your pointer to “What Our Clients Say” row. In the inspector box, you will see the pointed element with ID name which looks like
id=“pg-”. Please see this GIF https://cloudup.com/cFTDj1wGUvJ for more clearer understanding.
I hope this reply helps.
