Children in html.A not allowed?

Okay I figured it out.

According to this post , “html.H1(children=‘Hello Dash’) is the same as html.H1(‘Hello Dash’).”

So instead of doing html.A(“Help”,href="#",children=[html.P(“Please”)])
I should pass “Help” inside the children:

html.A(href="#",children=["Help",html.P("Please")])

Hope this helps whoever stumbles upon this problem same as myself in the future.
