[Answered ]-Rendering in django template paragraph behaves weird

It’s not Django doing this, its the browser “normalizing” what it sees as invalid markup. According to HTML spec, <p> tags can’t contain <ul> tags:

List elements (in particular, ol and ul elements) cannot be children
of p elements.

The spec recommends either closing the paragraph before staring the list: <p>...</p><ul>...</ul><p>...</p> (which is exactly what the browser did) or to use <div> instead of <p>.

To test, try downloading the page using wget and opening in a text editor – you’ll see that the generated markup is what you told Django to render, no extra tags added.
