Hi @bios2000one,
Thank you for reaching out, we do appreciate your time.
Unfortunately, dropdown rendering is largely in the control of the browser, meaning a CSS solution is not available in most cases as padding/margin values are ignored by the browser once the dropdown is opened.
We get around this by including non-breaking spaces ( ) to the output of the labels when we create the dropdown, and replicate that for each sub-branch within the hierarchy.
We can assist you with a custom solution to increase how many of these are included, but we aren’t allowed to do that via these threads. These forum threads are reserved for the basic version of the plugin, and as per the www.ads-software.com guidelines I do need to ask you to reach out to us on our website instead, so that we can assist you with this change.
Our filtering system is a premium feature and we are not allowed to provide premium support here, however, if you reach out on our site, we’d be happy to work through this with you. Please note, this thread will be marked as resolved as it does not directly relate to our basic plugin. We hope to hear from you soon.
