Hi,
I want to buy the Post grid Pro plugin but I need it:
1. I sneed to be able to select a specific category (of the post-type) to show
2. to be filterable by more than 1 taxonomy
ex.
Post-type: courses
Courses categories (tax):paddle,hike, climb
taxonomies filterable: duration( 1day,2 days,etc),level(1,2,3,etc.),start_date(1st Jan2020,2nd Feb 2020, etc)
So, I should be able to show on a page from the 'courses' post-type,
ONLY the category 'Paddle' and have a ajax search at the top with taxonomies data as shown in your video: https://www.youtube.com/watch?v=Zg2r7idmEm0
but better if as dropdown.
Can I do that with your plugin?

Welcome to our forum.
I am not sure if you already tried free version
https://wordpress.org/plugins/post-grid/
You can display custom post types and custom taxonomies, But filterable style only available in pro version.
#2, Yes you can filter by multiple taxonomies,
Please note search features is currently not available with filterable style grid, we are trying to add.
