Hi there,
We are sorry for the back and forth but let me explain few facts regarding the tab:
It is natural that JavaScript heavy elements such as sliders accordions or any element that the height is decided by JavaScript lose their height when loaded in a tab that is hidden at the first-page load. JavaScript code of the Inner element can not calculate the correct Heights because it is completely hidden.
The usage of the tab on your page is not what the tab meant to be. Try to use very simple elements inside tabs such as images and text.
Now regarding the case my colleague tried to give you work around with regarding the tab, the elements such as sliders re-render themselves when the window size is changed that is why in cases that The Slider is showing by resizing the browser window it will re calculate the height.
The latest code tries to force through calculation on each click of the tab. Now to make sure that the code will work correctly we will need to double check the case by Adding the codes ourselves by having the URL user pass of your website which you can give us using the secure note functionality
Also, I see that you already took off other tabs and only show one tab. Please kindly duplicate this page and add proper tabs there and get back to us with the URL of that page alongside the credentials that I asked for. Then we will try to make the suggested code work.
But again this is a temporary workaround and it will not change the fact that tabs are not supposed to use this way.
Thank you for your understanding.
