Hello，
When using markdown，I want to show the codetree in codeblock in additional to the markdown codetree. After checking the api，I find maybe the following method is helpful:
ed.set_prop(PROP_CODETREE_SUBLEXER, True)
However，after using that，the sublexer codetree didn't appear in codetree sidebar. Could you please give some guidance for how to do this？
Thanks！

this property allows sublexer (of current lexer, ie Markdown) to show sublexer nodes in the code-tree.
but Markdown don't have sublexer with code-tree support, or it does?

I use get_sublexer_range and see that code in codeblock will be token as sublexer (like python,JavaScript),but the codetree in codeblock can't been seen in sidebar.

I don't get it. give me the full lexer .lcf file (if it 's changed) and exammple markdown file.

only _changed_ Markdown lexer will be able to show sublexer nodes.
in the SynWrite's "Lexer properties" dialog you can see 'Sublexers' tab which setups included sublexers.

Maybe I misunderstand the usage of it.
For a file below，I want to show the python codetree in Sec3 in together with the original Markdown code tree，how to do that？

now I see what you mean. fenced code-block in Markdown.
I will study this. currently I don't know.

it cannot be solved. reason: code-tree is built here NOT using EControl engine, but using Pascal tree-helper for Markdown.
Pascal tree-helpers do not allow sublexer nodes. sorry.

I see，then what's the use of ed.set_prop(PROP_CODETREE_SUBLEXER, Ture)？ The description says: "PROP_CODETREE_SUBLEXER: bool: enable code-tree to show nodes from sublexer(s) of current lexer."
Sublexer means the user defined additional lexer for Markdown？
I find that the "# sec5" in fenced-block will not be recognized as Markdown title，that means if I define some additional lexer for Markdown，it will not be recognized in fenced-block？

BTW，where can I find the description about how to make pascal tree-helper for cudatext？I remember I've seen that before，that will be faster than python tree helper， right？
