good day dear Friends - hello everyone Smile 
at the moment i am working on a new WordPress-project.
and currently i am facing one certain issue: How to check if the post-type dropdown in the Query Loop block is populated with data?
outline: for a little test i have to do some quick lookup - i need to know if a “Post-Tpye” is visible in the so called “Post Type” drop-down?
How to do this check the certain drop-down: - where to start.
see some background: - and probably this may help here - since it has to do with the same topic - at least somehow
Using Query Loop with Custom Post Type
How to check if the post-type dropdown in the Query Loop block is populated with data?
outline: for a little test i have to do some quick lookup - i need to know if a “Post-Tpye” is visible in the so called “Post Type” drop-down?
some musings and assumptions: (how to achive this)
well i have made up my mind - and i think - that it should be doable like so:
well the step - thy could be like so;
… therefore i go to the the Query Loop Block
Inherit Query → OFF and then i should check:
Is the “Post Type” dropdown visible?
Are the certain post tpye - in my case “Foo-bar” selectable?
Does there “Test-story” appear?
all i need to know and i need to check is:
can i , I see post type “Foo-bar” in the dropdown
Or otherwise
No, the dropdown doesn’t appear.
Then we’ll know exactly where to start.
see some background: Using Query Loop with Custom Post Type
The post-type dropdown in the Query Loop block is populated with data from the REST API endpoint:
and yes - lets take for example:
/wp-json/wp/v2/types
The question is: so how to make sure the public custom post type is in a drop down menu - well therefore i think its necessary that it is registered with show_in_rest as true for it to be included within that data.
again - the background is: How to check the Post Type in the query-loop block:
well i think that i was recommended to go like so!
see some assumptions:
a. well to correctly configure the post type in the WordPress Gutenberg editor using the Query Loop block: we must select the outer container block. The Query Loop consists of several nested blocks, and only the parent block contains the settings for post type, number of posts, categories, and sorting.
b. Here’s how to select the outer “Query Loop” block:
Use List View (Recommended):
here we can do the following - we can click the icon that looks like three horizontal lines in the top left corner of the editor (List View). In the tree structure, find “Query Loop” and click it. This is the most reliable way to select the parent block.
c. Use Breadcrumbs:
Click an element within the loop (e.g., the post title).
In the editor footer, click the block path (Breadcrumbs) and select “Query Loop.”
d. Why this is important:
If we have selected the outer block, the “Post Type” option will appear under “Query” in the right-hand settings sidebar. Here we can specify whether to use “Posts,” “Pages,” or custom content types.
…well - these are some more theoretical assumptions - Can you confirm them - is it possible to do so!?
Look forward to hear from you
greetings
As a WordPress user myself, I would suggest you post this question in a WordPress forum. Wouldn’t that be more likely to get results that others in that community could also benefit from?
