On the sidebar, I'd like to make an automatic table of content that goes by categories. Let say I have 3 categories (Algebra, Geometry, Calculus) for all my posts, and I'd like my automatic table of content to look like this
1. How to factorise
2. Linear equation with 2 varibles
2. Integral - Calculate the area
3. Integral - Calculate the volume
4. Limit equations
1. Cubes (part 1)
2. Cubes (part 2)
4. Linear Graph
5. Pyramid (part 1)
6. Pyramid (part 2)
7. Pyramid (part 3)
I need it in alphabetical order and sequence of numbers..
Is it possible to make it in wordpress.com platform? How to do it?
Can anyone help me? Thanks in advance.
