click on labels.
4. Enter a label name which should also be a
name for your page and click done.
5. Now go to layout section of your blog.
6. Click on Add a gadget, select a Page gadget
appeared on the list.
7. Leave the Title as Page which is optional unless
you want to chage it to something else.
8. click on +Add External link. A page will appear.
9. Provide Title to your page and add a label link
and hit
save.
10. A label link is something like myblog.blogspot
.com/search/label/label_name
So if suppose, you want to add a page called Mobile
that should contain posts releated to mobiles, then
create post with label name as "mobile" and
add a
link to that label in steps 8. Your Mobile label will
look something like:
myblog . blogspot . com/search/label/mobile
Here replace myblog with your actual blogname and
mobile with your label name which you want to
create.
