Problem:

The question here is that the user anted to know if there is a Toolset block for the UX Builder in the flatsome theme.

Solution:

Unfortunately no we do not.
Having specific blocks would need to be done by both Flatsome and Toolset's compatibility teams. However you can still use Toolset with Flatsome by making use of our Toolset Shortcodes

Problem:
The user is using a 3rd party plugin to add an image to each taxonomy term. He would like to build a link around the image.

Solution:
Because of how the 3rd party plugin stores the image(in options table), it must be done using custom code. Toolset does not have built-in way to query the options table.
Check the custom code here https://toolset.com/forums/topic/adding-an-image-and-a-link-to-the-main-categories/#post-2199021
