How to check every field of MIGX element?

[[getImageList? &tvname=`Position_Item` &tpl=`@CODE:
    <div class="">
    
        [[+content:notempty=`
            [[+content]]
        `]]
        
        [[+btn_text:!empty=`
            [[+btn_text]]                   
        `]]
        
    </div>
`]]

if I check like a regular tv field it doesn’t show. I know the &toPlaceholder parameter but I need to check every element in MIGX.

Just to be sure, you are using a regular TV with the input type set to MIGX?

Try using a chunk with your template code instead of the inline @code. In general your setup looks fine to me, but I had similar issues before when using tag modifiers like :notempty within an inline tpl segment.

try to use a real tpl-chunk or replace [[ and ]] with {{ and }}

but why do you check, if empty at all? If the value is empty, it wouldn’t output anything, so you don’t need the check.
