Hello Dominic,

Thanks for writing to us.

The post loop builder does not support that option within the portfolio post type as of now - would require custom development, overriding the nectar_post_grid_item_markup function from plugins/salient-core/includes/post-grid/loop-markup.php which I'm afraid we are not able to offer due to support scope limitations.

However, we are partnered with a trusted provider of expert-level Salient customization. If you are interested in initiating a project, we recommend referring to our guide at the following link: https://themenectar.com/salient/customization/

In the meantime, please don't hesitate to reach out with further questions. We're happy to help.

Hey Again,

Please provide the page URL so we can write up what's possible.

Thanks.

Hey Again, 

Add this into the Custom CSS box in your Salient Theme Options panel (We write all Custom CSS in the Live Browser to ensure accuracy. If you cannot see any changes, make sure there is no red cross in the Custom CSS Box as any syntax error would cause all CSS under that line of code to not show up on the Frontend):

[data-columns="3"].layout-vert_staggered:not([data-text-layout="all_bottom_left_shadow"]) > div:nth-child(6n + 1) div.inner:before {
    background: none;
}
[data-columns="3"].layout-vert_staggered:not([data-text-layout="all_bottom_left_shadow"]) > div:nth-child(6n + 5) div.inner:before {
    background: none;
}

Thanks
