Reply To: Taxonomy using multi-select with search layout issue

Hi,

It is very likely due to the admin bar present on the page (it generates a negative margin relative to the body). If you test it on an incognito that it should look all right.

If this is a concern (ex.: your users see the admin bar), there is a way to offseet that via this custom CSS:

body:has(#wpadminbar)>span.asp_select2-container {
    margin-top: 32px !important;
} 

This should do the trick!
