Hello Gaston.

We are currently developing a better customization page, where you'll be able to hide all this through settings. For now, unfortunately, CSS is the way to go.

You don't have to worry, though - it will not hide anything before or after that screen, only what we tell it to hide. So, to hide "Capacity: X", you'll need to add this:

#am-service-booking > div > div.am-service > div.am-service-header > div.am-service-data > div.am-service-info > div:nth-child(1) {
display: none !important;
}

To hide the category:

#am-service-booking > div > div.am-service > div.am-service-info > div > div:nth-child(1) > div:nth-child(2) {
display: none !important;
}

And to hide "Photographers", you can use this:

#am-service-booking > div > div.am-service > div.am-service-info > div > div:nth-child(2) > div {
display: none !important;
}

All this needs to be above the [ameliacatalog] shortcode, in between the <style>...</style> tags, so like this:

<style>
#am-service-booking > div > div.am-service > div.am-service-header > div.am-service-data > div.am-service-info > div:nth-child(1) {
display: none !important;
}
#am-service-booking > div > div.am-service > div.am-service-info > div > div:nth-child(1) > div:nth-child(2) {
display: none !important;
}
#am-service-booking > div > div.am-service > div.am-service-info > div > div:nth-child(2) > div {
display: none !important;
}
</style>
