What is the current behavior?

I want to limit HTML to given subset defining valid_children: '-h1[b],-h2[b],-li[h1|h2|ul|ol],-ul[ul|ol],-ol[ul|ol]'.

Provided this configuration it's possible to create nested list with TAB key and by pasting it from already existing HTML. Here is an example of a nested list:

• Coffee
• Tea
  • Black tea
  • Green tea
  • Green tea
• Milk

**If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem via fiddle.tinymce.com or similar.

What is the expected behavior?

It's not possible to create a nested list by a TAB key or by pasting it from already existing HTML. The pasting should strip nested list tags (ol, ul, li).

Which versions of TinyMCE, and which browser / OS are affected by this issue? Did this work in previous versions of TinyMCE?

I was able to reproduce it with various 4.* versions.

Hi,

Any update on this? Have you found a fix/workaround @hjagodzinski ?

I have the exact same problem, restrictions expressed by valid_children are not taken into account...
Tested on v5.10 and v6 of TinyMCE, no success...

Update :

Provided this configuration it's possible to create nested list with TAB key

For that part, you can set the option lists_indent_on_tab (from lists plugin) to false to prevent creating nested lists by pressing TAB on an existing list item

But still, the current config valid_children: '-li[h1|h2|ul|ol],-ul[ul|ol],-ol[ul|ol]'. still does NOT prevent nesting lists through Copy-Paste into the editor....
The reason is certainly because the internal Schema add this explicitly:

tinymce/modules/tinymce/src/core/main/ts/api/html/Schema.ts

Line 852 in d19d30f

addValidChildren('+ol[ul|ol],+ul[ul|ol]');
