Taxonomy Parent Term page with Child Terms and their description + teasers (with condition)

I’m working on a website with several vocabularies. Two of them are build like this :

• Parent Term
• • Child term#1
• • Child term#2
• • Child term#3

Only one parent and some children.

I have two Content Type, each uses one of these two vocabulary. When I create a node I can set only one term (the reference field is a drop-down list).

For the first vocabulary I’d like to show on the Parent Term page all of his Child Terms with their Description and Teasers that are related to them :

• h1 (Parent Term)
• h2 Child Term#1 + Term description + Teasers
• h2 Child Term#2 + Term description + Teasers
• h2 Child Term#3 + Term description + Teasers

For the second vocabulary I’d like to show the same thing one the Parent Term page but with a specific filter. If the Child Term possesses a boolean field set on FALSE then the teasers are not showing and a link to the Child Term page appears :

• h1 (Parent Term)
• h2 Child Term#1 (boolean TRUE) + Term description + Teasers
• h2 Child Term#2 (boolean TRUE) + Term description + Teasers
• h2 Child Term#3 (boolean FALSE) + Term description + link to Child Term#3 page

I know some basics with Views, Page Manager and Panels and I think this is a pretty basic configuration but for some reasons I don’t understand how to do it…

Thanks
