how to display a list of tags, which are not mainTags

[3muchfun]

Dear all,
I use the code below and I would like to change it to display tags which are not mainTags, only.
Maybe one of you can help me out...

{{#checkIfAny @config.post.displayTags @config.post.displayShareButtons }}
    {{#if @config.post.displayTags}}
        {{#if tags}}
            {{#each tags}}
                {{#checkIf @index '>' 0}}, {{/checkIf}}
                <a href="{{url}}">{{name}}</a>
            {{/each}}
        {{/if}}
    {{/if}}
{{/checkIfAny}}

I haven't tested this code, but just by taking a quick look, I'm not sure why the {{checkIf}} statements are next to each other, separated by a comma. I tried to fix the formatting so it compiles correctly.
I also got rid of an unnecessary space in the top statement.
Does this help?

{{#checkIfAny @config.post.displayTags @config.post.displayShareButtons}}
    {{#if @config.post.displayTags}}
        {{#if tags}}
            {{#each tags}}
                {{#checkIf @index '>' 0}}
                    <a href="{{url}}">{{name}}</a>
                {{/checkIf}}
            {{/each}}
        {{/if}}
    {{/if}}
{{/checkIfAny}}

Thanks for your answer, @kryptot7.
The code I mentioned was provided by @bobmitro here and works fine. Secondly, I am missing the " , " in your code to create the comma separated list.
My question is, how can I filter the tags to show mainTags, only.

@candidexmedia, do you have any idea on how to achieve that?

[candidexmedia]

Not sure if you still need help with this, but because mainTag is still new, and the dev docs have some gaps, it's hard to know what syntax to use. I'm also not a pro at handlebars / JS.

My hunch would be to add some sort of "not equal" argument, kind of like what's explained for checkIf. Maybe @HowToMeetLadies has some ideas?

Sidenote for Publii devs & community: I would love to see some kind of crowd-sourced, searchable database/repo of code snippets for theme developpers, beyond the docs.

Wanted to add: the Handlebars documentation might also have some clues:

https://handlebarsjs.com/guide/builtin-helpers.html#if

https://handlebarsjs.com/guide/builtin-helpers.html#each

Adding the note for reference for a solution in the meantime @3muchfun : #1329 (comment)

In Publii v.0.46 there will be isMainTag flag available inside tag items in tags:
bca2160

[candidexmedia]

Sweet!

So the syntax would be something like this?

{{#checkIf tags.isMaintag = false}}
...
{{/checkIf}}

[dziudek]

@candidexmedia even simpler:

{{#unless isMainTag}}
...
{{/unless}}

[3muchfun]

Thanks for your answers, @candidexmedia , @dziudek .
So, with this new "isMainTag", I can differ between tags and MainTags?
At the bottom of each post I want to show the Category aka MainTag, and in a second row, the Tags, aka the tags which are not MainTags.
