[Closed] Create a Filter view by custom taxonomy that shows only the sub category terms

Hi there,

I was wondering if a filter view by custom taxonomy that shows only the sub category terms possible to create with the Toolset view plugin.

I am planning to create a site that has a Custom Post Type 'Events' and a custom taxonomy called 'Event Categories'.
The 'Event Categories' will have 2 levels (parent level & a secondary level), example below.

Infants (<- parent level)
- drop ins
- after school programs
Adults (<- parent level)
- camps
- fitness

Say I want to create a page called 'Infants', and I would like to create a filter view by custom taxonomy that shows only the sub category terms from the 'Infants' parent category level.
So excluding the parent level term name 'Infants' and excluding the 'Adults' parent level + the 'Adult' sub categories, ONLY showing 'kids dropins' + 'after school programs' terms in checkbox fields.
I know by default, it shows all the category terms in the filter view, but is there a way to ONLY show the sub category terms from one of the parent level category or somehow hide/exclude the ones that I don't want to show in the filter view?

I have attached an image that demonstrates how I would want to look like.

Thank you!

Hi Paul,

Thank you for getting in touch.

Unfortunately no this is not possible to achieve because you are not able to create a filter to filter out the Parent terms and just display the child terms.

What you can do is to use a select field which I believe would display your child/parent terms like below.

Parent A
-Child A
-Child B
Parent B
- Child C

Given that the Parent and Child Terms are one Taxonomy there isn't a way to separate them into Parent and Child.

Thanks,
Shane

Thank you Shane !

I found in this article (https://toolset.com/forums/topic/exclude-a-taxonomy-from-a-search/) that could exclude specific taxonomies from showing in a taxonomy filter/search. Would this work?

Also, since I would like to exclude specific taxonomies in the filter/search, is there a way to hide/exclude posts from the search result that are labelled with taxonomies I want hidden ?

Parent A
-Child A
-Child B
Parent B
- Child C

Say I want to only show 'Child A' & 'Child B' in the filter/search, then I would want to display posts that are labelled with 'Child A' & 'Child B' in the search result. Is there a way to do that?

Thanks, Rose

Hi Paul,

The code in the link below is only to exclude taxonomy terms that you don't want to be added to the filter at all.

Also, since I would like to exclude specific taxonomies in the filter/search, is there a way to hide/exclude posts from the search result that are labelled with taxonomies I want hidden ?

Are you building your search using the Toolset Block editor ? Or are you creating it using the Classic editor by going to Toolset -> Views -> Add New.

Please let me know so that I can provide the instructions.
Thanks,
Shane

Hi Shane,

Yes, I want to exclude taxonomy terms that I don't want to be added to the filter, would that code work?
I am building the filter/ parametric search with the Classic editor 'Toolset View'.

Thanks!

[Shane]

Hi Paul,

Given that you are using the Classic editor you can try this:
1. Go to your view and edit it.
2. Scroll to the section that says "Custom Search Settings "
3. Select "Let me choose individual settings manually"
4. Then go to "Which options to display in the form inputs"
5. Finally Select " Show only available options for each input"

Once you've done this please let me know if only the Posts that are for the available taxonomies on your search appear.

Thanks,
Shane

Thanks Shane!

It seems that your method doesn't work for me.

I've used the code from this article (https://toolset.com/forums/topic/exclude-a-taxonomy-from-a-search/). The code works to hide/exclude taxonomy terms in the parametric search filter, so ONLY displaying 'Parent A' child terms ('Parent A Child 1' + 'Parent A Child 2') in the taxonomy filter and hide the rest (which I want).

Parent A (HIDDEN)
- Parent A Child 1
- Parent A Child 2
Parent B (HIDDEN)
- Parent B Child 1 (HIDDEN)
- Parent B Child 2 (HIDDEN)
Parent C (HIDDEN)
- Parent C Child 1 (HIDDEN)
- Parent C Child 2 (HIDDEN)

For the search result, I want to exclude some terms from the search result.
I want to hide/exclude posts labelled with taxonomies I have hidden. So ONLY displaying posts labelled with the terms Parent A Child 1, Parent A Child 2.
I've found this article (https://toolset.com/forums/topic/exclude-some-taxonomy-terms-from-filter-search/) that excludes posts labelled with certain taxonomy terms from the search result using a filter hook (wpv_filter_query) added to the functions.php file.
It does work as I wanted to, where it only displays posts labelled with the term Parent A Child 1, Parent A Child 2.

Is there a simpler method to do this in the Toolset View interface without having to do this entirely through code?

Thanks!

Hi Paul,

The method would be a combination of the custom code here https://toolset.com/forums/topic/exclude-some-taxonomy-terms-from-filter-search/

As well as the settings that i've defined in my previous thread here https://toolset.com/forums/topic/create-a-filter-view-by-custom-taxonomy-that-shows-only-the-sub-category-terms/#post-1660639

So you will need to adjust the settings and use the custom filter. If this is what you've done please let me know.

No there isn't since this is outside of the normal use case, you will need to use custom coding to achieve.

Thanks,
Shane
