1. Navigate to WP Tabs Pro → Click on Add New to Add New Tab Group.
2. Type a Title for your tab group.
3. Select any tab type you want from the Tabs Type option. Two options are available:
- Content
- Post
4. Under the Display Options you will find the Active Tab Style option with three positions. Choose any of them as per your requirements. The options are:
