Dear Fabien Raveton,
Maybe you can set the duration in the css file.
Please go to "modules\mod_sj_content_reslisting\assets\css\sj-reslisting.css", finding:
.sj-responsive-listing .item-inner .item-more{
top:0;
left: 0;
bottom:0;
right:0;
overflow: hidden;
position: absolute;
visibility:hidden;
height:0;
-webkit-transition: all 0.5s ease-in-out;
-moz-transition: all 0.5s ease-in-out;
-ms-transition: all 0.5s ease-in-out;
-o-transition: all 0.5s ease-in-out;
transition: all 0.5s ease-in-out;
}
=>
.sj-responsive-listing .item-inner .item-more{
top:0;
left: 0;
bottom:0;
right:0;
overflow: hidden;
position: absolute;
visibility:hidden;
height:0;
-webkit-transition: all your_time ease-in-out;
-moz-transition: all your_time ease-in-out;
-ms-transition: all your_time ease-in-out;
-o-transition: all your_time ease-in-out;
transition: all your_time ease-in-out;
}
Example: your_time as 0.6s, 0.7s, 0.8s, ...
Thanks
