Hi kewal_tech and welcome to our community
Normally you do this as follows:
1. Right click the Templates pseudo folder and define a new
template.
2. While editing the Template, add your Header and Footer
informaton.
3. Once this is done, click the Topics tab on the lower
right.
4. Click once on any topic. Then press Ctrl+A to select all
topics.
5. Right click the list of selected topics and choose
"Properties" from the context menu.
6. Click the General tab.
7. Click the drop-down and choose the new Template you
created.
Voila!
Cheers... Rick
