There is a code that output is already cf7 in the browser

<span class="wpcf7-form-control-wrap mkdf-s">
<select name="mkdf-s" class="wpcf7-form-control wpcf7-select mkdf-select" aria-invalid="false"><option value="1">1</option><option value="2">2</option>
></select></span>

and i would like to insert my class

<span class="wpcf7-form-control-wrap mkdf-s my-class">

someone did this, there is no information in the documentation.

Answer 1

<span class="my-class1">[select menu-594 class:my-class2]</span>

my-class2 - added directly to the select
my-class1 - wraps the select and its wrapper
But to add a wrapper, you can try what niaccurshi advises here, maybe it will do . Simple solutions even failed to google
