Problem:
How can we add Toolset custom fields to the quick edit sections of posts, where those fields are assigned to?
Solution:
That's not possible without Custom Code, which we cannot provide as such in the support forum.
The only particular to Toolset here is that Toolset Custom Fields will have a slug prefix of "wpcf-"
The rest is like handling native WordPress Fields for a quick edit, this is why we cannot provide any particular help with the custom code, as it doesn't make usage of Toolset Features.
Note that Taxonomy Terms can be added to quick edit mode.
You can also display a few (not all) Custom Fields as well in the posts admin list, but that does not allow any editing.
If you choose to use Custom Code, please acknowledge that there is an issue which we are aware of, see here the tickets:

https://toolset.com/forums/topic/information-disappears-after-custom-post-is-put-in-draft-on-quick-edit
Generally, when you'd add_action to quick_edit_custom_box hook (https://developer.wordpress.org/reference/hooks/quick_edit_custom_box/) and save_post to save the data quick edited, some layout errors will happen on the posts admin list.
This will be looked at in future development of Toolset, hower there is no plan to incorporate it directly as a feature.
I suggest requesting the feature here:
