I'm trying to do Taxonomy archive template (with blocks) "Tags" for multiple post types Posts, Reviews, Webinars and other.
How to display posts first, then webinars, then reviews on one page, so that each post type is in a separate view.
Now they are all in order of publication date, no sorting.
You are using the legacy editor for custom archives, would that be right?
You can see in the screenshot I have a custom archive for tags that includes multiple post types in the results, and in the order option I can specify the post type for ordering by.
That will group the results according to post type, but it doesn't allow for providing any kind of heading or divider between the different types of post, for example.
If you required that the you would need to add separate Views for each post type to output in place of the archive results.
Sorry, I omitted the screenshot, I'm attaching it now.
It's from the legacy editor, where you can specify the post types to be included.
Unfortunately the same option isn't available when using the Block editor. It will get added, but isn't available yet.
There is a workaround, however.
Create the custom archive with the legacy editor and set the content options to include the post types you require, if you then choose to switch to the Block editor for the archive it will remember the post types you had previously selected, even though you cannot see or change that option.
The Toolset WordPress Archive can only format/style the results, it can not group the results by post types.
In your case, you will need to create three post views, each one query one post type, and filter by:
Select posts with taxonomy:
Tags the same as the current archive page
Then insert above three post views shortcode into the Toolset WordPress Archive.
If you are using Blocks Editor to setup the WordPress Archive, you need to put those three post views outside the "WordPress Archive Loop" block
