You can use isset() function to check if it has a value. In your case you can do like this : $width = get_post_meta( $post->ID, ‘iswidth’, true ); if( isset( $width ) ){ echo “<li>Width (px): “.$width.”</li>”; }
You can create something similar to WYSIWYG link dialog by generating traditional HTML SELECT with OPTIONs as post items, and then make it more interactive (searchable,…) with Chosen jQuery library. It’s not as precise solution as that in editor, but it can be enough for you.

It seems that at that point, $post is not yet defined, you can make sure by turning debugging on. Then add this before your get_post_meta( $post…: global $post; Or you can replace $post->ID with get_the_ID().
According to ACF Docs on Get values from an options page. You should use ‘option’ not ‘options’ as the second parameter to the have_rows() function. <?php if( have_rows(‘repeater’, ‘option’) ): ?> <ul> <?php while( have_rows(‘repeater’, ‘option’) ): the_row(); ?> <li><?php the_sub_field(‘title’); ?></li> <?php endwhile; ?> </ul> <?php endif; ?>
