not responsive on mobile

You can fix this easily.

Set the width to be a percentage (eg 70%) and then edit the following file in the plugins folder:

/css/itro-style-functions.php

About half way down under the #itro_popup class you need to add a “max-width” tag. Here is my code. Not the last line, this is the one you will need to add, the other code is just to help you find where it is.

width: <?php if( itro_get_option('select_popup_width') == 'px') { echo itro_get_option('px_popup_width') . 'px'; }
	if( itro_get_option('select_popup_width') == 'perc') { echo itro_get_option('perc_popup_width') . '%'; }?>;
	max-width: 500px;

Now just change the value of the max-width until you’re happy with how it looks.
