Hi,

I fixed it for you. I used this code:

 */
if ( ! defined( 'ABSPATH' ) ) {  exit;  }    // Exit if accessed directly

		/**
		 * Create the config array for the shortcode button
		 */
		function shortcode_insert_button()
		{
			/**
			 * inconsistent behaviour up to 4.2: a new element was created with a close tag, after editing it was self closing !!!

so the one method works with permanent Tooltip Window open !
so we than go and do the rest with quick css:

.avia-tooltip {
    opacity: 0;
    display: none !important;
}

.av-image-hotspot:hover .avia-tooltip {
    display: block !important;
    opacity: 1 !important;
}

this is what comes to functions.php of your child theme:

function ava_tooltip_script() {
?>
<script type="text/javascript">
	(function($) {
		function b() {
			$(".inner_tooltip a").magnificPopup({
	    		type: 'iframe',
	    		mainClass: 'avia-popup mfp-zoom-in',
	       	});
		}
		$(window).load(function() {
			b();
		});
	})(jQuery);
</script>
<?php
}
add_action( 'wp_footer', 'ava_tooltip_script' );

see here: https://webers-testseite.de/image-with-hotspost-linking-to-youtube-in-iframes/

the thing is that the tooltip window (hotspot image on the bottom of my link) only arises when hovering the tooltip
it does not exist in the DOM till hovering – so my code here: Link has no influence on it.
Even the DOMNodeInserted function does not work here

next problem i changed in avia-modal.js the ( i tried both lines ) from mouseenter to click
but it does not work (even after clearing all caches)

best solution was in my opinion if we let the mouseenter event – but
the window must stay open till a link is clicked in the inner tooltip.

on line 1498 of avia.js : $.AviaTooltip = function(options)

do we have to change something additional to the avia-modal.js?

so we can force the links inside the inner_tooltip to open in lightbox by this snippet in functions.php of the child-theme:

add_action( 'wp_footer', 'ava_tooltip_script' );
function ava_tooltip_script() {
	?>
	<script type="text/javascript">
	(function($) {
		function b() {
			$(".inner_tooltip a").magnificPopup({
	    		type: 'iframe',
	    		mainClass: 'avia-popup mfp-zoom-in',
	       	});
		}
		$(window).load(function() {
			b();
		});
	})(jQuery);
	</script>
	<?php
}

so now see page: https://webers-testseite.de/image-with-hotspost-linking-to-youtube-in-iframes/

this is not the solution – it is a styling point of view.
If you set the tooltip alway visible (see link above) the inner link (inner_tooltip) does not link in lightbox – allthough the image has the iframe=true thing.
So for me it would be nice to open the tooltip on click ( you will use than instead of mouseenter the click event) – and then click on the image in the tooltip to oben the lightbox.
But i do not realy know why the link does not open in lightbox.

on this case you had to change to click event and not on hover tooltip.
This is set in avia-modal.js in line 903ff

/*highlight the modal sub el when hotspot is hovered*/
   				_self.hotspot_container.on('mouseenter', '.av-image-hotspot', function()
   				{
   					var el = $(this).data('modal_sub_el');
   					if(el) el.addClass('av-highlight-subel');
   				});

maybe than it would be possible to have a link in the tooltip window opening on lightbox.
The problem then would be that the tooltip is itself a “popup-window” – but you like to open it in a new lightbox window.

Hey Roger,

The gallery element does not display the copyright information by default. However you could i.e. add the copyright information to the caption/popup tooltip by replacing line 320 in enfold\config-templatebuilder\avia-shortcodes\gallery\gallery.php

$caption = trim($attachment->post_excerpt) ? wptexturize($attachment->post_excerpt) : "";

with

$caption = trim($attachment->post_excerpt) ? wptexturize($attachment->post_excerpt) : "";

$copyright_text = get_post_meta($attachment_id, '_avia_attachment_copyright', true );

if($copyright_text) $caption .= ' ' . $copyright_text;

Best regards,

Hi,

I’m not familiar with the plugin (we didn’t test it with Enfold and we can’t support it) but probably it uses the standard google maps api: https://developers.google.com/maps/documentation/javascript/tutorial like Enfold to embed Google maps. It seems like the plugin removes the Enfold maps code (i.e. the code I asked you to add to your functions.php is missing but there’s even more is missing, i.e. the coordinates of the maps marker, etc.) and thus the maps won’t work.

On the demo page here: https://kriesi.at/themes/enfold-2017/pages/contact/ for example the coordinates and map styling code looks like:

<script type='text/javascript' class='av-php-sent-to-frontend'>/* <![CDATA[ */ 
var av_google_map = {};
av_google_map['av_gmap_0'] = {};
av_google_map['av_gmap_0']['marker'] = {};
av_google_map['av_gmap_0']['marker']['0'] = {};
av_google_map['av_gmap_0']['marker']['0']['address'] = "Main Street, California";
av_google_map['av_gmap_0']['marker']['0']['city'] = "";
av_google_map['av_gmap_0']['marker']['0']['country'] = "";
av_google_map['av_gmap_0']['marker']['0']['long'] = -79.88742450000001;
av_google_map['av_gmap_0']['marker']['0']['lat'] = 40.0577507;
av_google_map['av_gmap_0']['marker']['0']['marker'] = 2078;
av_google_map['av_gmap_0']['marker']['0']['imagesize'] = 80;
av_google_map['av_gmap_0']['marker']['0']['tooltip_display'] = "";
av_google_map['av_gmap_0']['marker']['0']['av_uid'] = "av-3e0e9c";
av_google_map['av_gmap_0']['marker']['0']['icon'] = "https:\/\/kriesi.at\/themes\/enfold-2017\/wp-content\/uploads\/sites\/66\/2017\/02\/marker3.png";
av_google_map['av_gmap_0']['hue'] = "#35383c";
av_google_map['av_gmap_0']['zoom'] = 16;
av_google_map['av_gmap_0']['saturation'] = "fill";
av_google_map['av_gmap_0']['zoom_control'] = 1;
av_google_map['av_gmap_0']['streetview_control'] = false;
av_google_map['av_gmap_0']['pan_control'] = false;
av_google_map['av_gmap_0']['mobile_drag_control'] = 1;
av_google_map['av_gmap_0']['maptype_control'] = "";
av_google_map['av_gmap_0']['maptype_id'] = "";

 /* ]]> */</script>

and this code is completely missing on your website. Unfortunately you can’t simply fix this by adding this code to the child theme functions.php file because it’s generated dynamically for each map element based on your map settings (styling of the map, coordinates, marker image, etc.).

Best regards,
Dude

the most easiest way would be to register a new social media button for example with a lock and have the rounded buttons as if it was a social media link – on hovering you can see the tooltip : registering.
i do this often for links like intranet link or login links.
this could be handeled than like on my link above – because than it is part of social-media list.

See here Result ( i do not change to see only burger-menu – so have a look at smaller screensizes )
https://webers-testseite.de/cynthia/

if you like to insert for example a whole avia button shortcode – that is possible too.

add_action('ava_inside_main_menu', function() {
  echo '<li class="registerbutton">';
  echo do_shortcode("[av_button label='Register now' link='manually,#' link_target='' size='large' position='left' label_display='' icon_select='yes-right-icon' icon_hover='aviaTBicon_hover' icon='ue875' font='entypo-fontello' color='custom' custom_bg='#42ab96' custom_font='#ffffff' av_uid='av-b9l' custom_class='' admin_preview_bg='']");
  echo '</li>';
});

function change_menu_position() { 
?>
<script>
(function($){
	$('.main_menu ul.social_bookmarks').insertBefore($('.main_menu div.avia-menu'));
	$('li.registerbutton').appendTo('.main_menu > .social_bookmarks');
})(jQuery);
</script>
<?php
}
add_action('wp_footer', 'change_menu_position');

the code can be obtained by activation of the debug mode on enfold for above rules
– echo do_shortcode(" into this comes the full shortcode of your avia button ");

this comes to quick css:

/*** this is for the new button not to have same behavior as social_bookmarks buttons ***/
.registerbutton { width: auto !important }
.registerbutton .avia_button_icon { display: inline-table }
.social_bookmarks li.registerbutton a { border-radius: 0 !important; padding: 0 10px !important; width: auto !important; background: #42ab96; color: #fff }

/*** rules for the left-hand social_bookmarks buttons ***/
#top nav .social_bookmarks { margin-top: -20px !important; overflow: visible !important; height: 40px !important }
.avia-menu.av_menu_icon_beside { padding-right: 0; margin-right: 0; border-right-width: 0; border-right-style: none }
.social_bookmarks li a { height: 40px !important; line-height: 40px !important; width: 40px !important }
#top .social_bookmarks li { width: 40px; height: auto !important }
#top .av-logo-container .social_bookmarks li a {  border-radius: 50% }
.av_header_transparency .social_bookmarks li a { color: #969696 !important;}

can you try this in your functions.php of your child-theme:
this filter you will only need if you havn’t got a secondary menu or social media – so there will be no header-meta
add_filter( 'avf_execute_avia_meta_header', '__return_true', 10, 1);

for you this will be enough i think:

add_filter( 'avia_meta_header', 'avia_append_search_nav_mod');
function avia_append_search_nav_mod()
{
          global $avia_config;
          ob_start();
          get_search_form();
          $form =  htmlspecialchars(ob_get_clean()) ;

          $items .= '<li id="menu-item-search" class="noMobile menu-item menu-item-search-dropdown menu-item-avia-special">
                        <a href="?s=" data-avia-search-tooltip="'.$form.'" '.av_icon_string('search').'>
                          <span class="avia_hidden_link_text">'.__('Search','avia_framework').'</span>
                        </a>
                    </li>';

    echo $items;
}

Edit: i see it has on header meta a list-point so add this to your quick css:

#top #menu-item-search {
    list-style: none;
}
