Hello @s_paced,
The contents for the “teams” and “testimonial” sections come from the widget “EH:Teams” and “EH:Testimonial Slider” widgets in Appearance > widgets section. Create a team category and add posts for individual team member. The post title, featured image and excerpt will be used to display team members details.
You can select your post category and no. of posts you want to display in the team section and similarly in the testimonial slider.
Feel free to write down for any more confusions.
Best Regards!!
Have a great week ahead.
