Hi again,
You can try adding the following code in the Theme Options > JS:
function sameHeightSection(section) {
var max = 0;
var sections = jQuery("." + section);
sections.each(function(index, el) {
if( jQuery(this).height() > max ){
max = jQuery(this).height();
}
});
jQuery("." + section + " > .tg-item-inner").css({
'height': max,
'min-height': max,
'max-height': max
});
}
jQuery(document).ready(function($) {
sameHeightSection('tg-item');
});
jQuery(window).resize(function(){
sameHeightSection('tg-item');
});
As you see this requires custom development and the code provided above serves as a guide only and is to help you in getting started so implementing it and maintaining the code will be out of our support scope and for further maintenance for new possible versions of the theme that may cause the customization to break, you will need to hire a developer.
Thank you!
