1. How do you delete taxonomies: Cleaning up my post page.
2. Hierarchical taxonomies: Each one of my posts can belong to multiple categories. However, each category also belongs to parent categories. can I make this connection after I've imported all my data? See the uploaded picture: I want to create the parent categories and drag the other categories under it.
3. If I am upload a image from a URL to a field group, do I use the image or url widget?
Taxonomy terms are managed using the normal WordPress UI.
If you assigned a taxonomy "sectors" to a post type "investments" then from the WordPress dashboard you would go to Investments > Sectors to arrive at the page to manage the terms of the sector taxonomy.
From there you can add and delete terms, and when you edit terms you have the option to set a parent. There may be plugins available to offer a better UI for doing that, but I'm not familiar with any.
Can you clarify what you mean by 3?
Typically you would add an image field to a custom field group assigned to some post, upload an image when editing the post, and then if you are making a template to show these posts and you want it to output the image you would do so using the Image block.
But it sounds like you may be doing something different, can you clarify?
So when I'm making the field group, should it be an image or and URL because the image isn't uploaded because it is retrieved from an URL.
Ok so in a case like this you can use either a single field or a URL field, however I would recommend a URL field given that when you can use the raw attribute to get the exact URL back from the database.
So what you will need to do is to manually wrap the image in the img tags when you want to display it on the frontend.
