Current behaviour

Hi,

I use Outline to create links by right-clicking on headers:

The Problem is that the link is not clickable when it contains a ticked checkbox: [x]

When a heading contains a ticked checkbox, the Outline plugin generates a link like this:

[My note#[x] title](:/131d7ddac2e94ec7a86e90631f47fbae#x-title)

In the editor, instead of the whole label being rendered as a clickable link, only the [x] part appears highlighted in blue, and the link cannot be followed with Ctrl+Click:

An issue about links and checkboxes was originally discussed in the Rich Markdown plugin (CalebJohn/joplin-rich-markdown#63), but for this actual problem, I tested with Rich Markdown disabled (and all my other plugins disabled too), and the same rendering issue occurs, so this may be a Joplin core bug.

If the checkbox is unticked ([ ]), the link is fully blue and clickable.

Expected behaviour

Links containing a ticked checkbox should work.

My idea for a solution

If checkboxes in headings were ignored when generating anchors, the link would always work and it could also resolve this other issue: #15057 .

Workaround I'm currently considering

Only use unticked checkboxes in headings, and delete them when a task is finished (instead of ticking the box). I think it would work, but it's not as natural as ticking the checkbox.

Happy to provide any additional test cases or clarifications.
Thanks :)

Hi,

I don't know if this helps, but it seems to me that as soon as there is one or more characters in square brackets, even if it is not a ticked checkbox, the link breaks.

Note that the behavior differs depending on the link type:

For internal links:
[My note#[anything] title](:/131d7ddac2e94ec7a86e90631f47fbae#x-title):
Rendered in editor:

The whole link becomes non-clickable

For external links:
[[anything]Internal links with checkboxes in headings: not clickable when ticked · Issue #15056 · laurent22/joplin](https://github.com/laurent22/joplin/issues/15056)
Rendered in editor:

The URL (in parentheses) remains clickable, but the link isn't rendered with only its title anymore.
