Hello there! This is Jamal from Toolset support. If you don't mind, I'll continue with you on this ticket.
Currently, Toolset does not offer a way to customize the markup of the generated elements. Some of Toolset CSS classes are crucial to Javascript code. For example AJAX searches and paginations, conditional display of form fields. Some CSS classes are used for styling, especially for Blocks.
We do have some hooks that you can use to customize the generated markup, such as:
- wpv_filter_content_template_output for content templates output.
- wpv_filter_start_filter_form and wpv_filter_end_filter_form for the output of the search section.
- wpv-post-field-meta-{$name} for the output of fields.
Read more about them and other interesting filters here https://toolset.com/documentation/programmer-reference/views-filters/
However, I think that you can customize the styling of Toolset components by generating CSS that uses Toolset classes and styles from the Tailwind framework, by using the "apply" directive from the framework. Read more about it here hidden link
I hope this helps. Let me know if you have any questions.
