Hi!
1. Yes, you can either use the taxonomy term filter, or use hard-restrictions without the filter to include results from specific categories/terms only
2. Yes, you can, here
3. You can change the layout mode of the filters. Multiselect with search is the closest to a button layout.
4. The tag buttons in the ‘Multiselect with search’ section are hard-coded via a 3rd party script. I would say it is not impossible, but defintely very hard via custom CSS.
5. No, at least not without major customizations
6. If you mean the checkboxes within one single taxonomy filter, it is possible by using custom CSS:
[html].asp_w fieldset.asp_tax_filter {
min-width: 100% !important;
width: 100% !important;
}
.asp_tax_filter .asp_option {
float: left;
margin-left: 10px !important;
}[/html]
7. If you mean the filter, then yes. Using the settings shortcode. Place this shortcode above the search shortcode above the search shortcode.
8. Yes. In that case, please do not use the settings shortcode as suggested above, just the search shortcode, as it will be automatically converted.
9. No
10. You can use the results shorcode to move the results on the same page from below the search bar to somewhere else on the same page.
11. No, I don’t think that will work
12. No, only the wordpress search results page query is designed for the override. Combining multiple plugin elements to interact with each other is usually very difficult, and hard to maintain. If there is a built-in Elementor widget or add-on for this purpose, that might be capable of that, I am not sure.
