In this section we will enable nested comments by modifying COMMENTS_XTD_MAX_THREAD_LEVEL and apply some changes to our blog_detail.html template.

We can make use of two template tags, render_xtdcomment_tree and get_xtdcomment_tree. The former renders a template with the comments while the latter put the comments in a nested data structure in the context of the template.
